imap_open

(PHP 4, PHP 5)

imap_open — メールボックスへの IMAP ストリームをオープンする

説明

resource imap_open ( string $mailbox , string $username , string $password [, int $options = NIL [, int $n_retries = 0 [, array $params = NULL ]]] )

mailbox への IMAP ストリームをオープンします。

この関数は、POP3 や NNTP サーバへのストリームをオープンする際にも使用可能です。しかし、いくつかの関数および機能は IMAP サーバでしか利用できません。

パラメータ

mailbox

メールボックス名(mailbox)は、サーバ名の部分と使用するサーバにおけるメールボックスへのパスから構成されます。特別な名前 INBOX は、カレントユーザの個人メールボックスを意味します。 ASCII 空間で出力可能な文字以外の外国文字を含むメールボックス名は imap_utf7_encode() でエンコードする必要があります。

サーバ部は '{' および '}' で括られ、サーバ名または IP アドレス、オプションの ':' から始まるポート指定子、('/' で始まる)オプションのプロトコル指定子から構成されます。

サーバ部は、全ての mailbox パラメータで必須です。

{ で始まる名前はすべてリモート名で、 "{" remote_system_name [":" port] [flags] "}" [mailbox_name] のような形式となります。

remote_system_name - Internet ドメイン名あるいは括弧でかこまれたサーバの IP アドレス。
port - オプションの TCP ポート番号。デフォルトはそのサービスのデフォルトポート。
flags - オプションのフラグ。以下の表を参照ください。
mailbox_name - リモートメールボックス名。デフォルトは INBOX 。

**オプションのフラグ名**
フラグ	説明
/service=service	メールボックスにアクセスするサービス。デフォルトは "imap" 。
/user=user	サーバへのログイン時のユーザ名。
/authuser=user	リモートの認証ユーザ。指定されていた場合は、このユーザのパスワードが認証に使用されます（例: administrator）。
/anonymous	匿名ユーザとしてアクセスします。
/debug	プロトコルの通信内容をアプリケーションのデバッグログに記録します。
/secure	ネットワーク越しにプレーンテキストのパスワードを送信しません。
/imap, /imap2, /imap2bis, /imap4, /imap4rev1	/service=imap と同じです。
/pop3	/service=pop3 と同じです。
/nntp	/service=nntp と同じです。
/norsh	事前に認証済みの IMAP セッションを確立する際に、rsh や ssh を使用しません。
/ssl	セッションの暗号化に Secure Socket Layer を使用します。
/validate-cert	TLS/SSL サーバの証明書を検証します（デフォルトの挙動です）。
/novalidate-cert	TLS/SSL サーバの証明書を検証しません。サーバが自己証明の証明書を使用している際に必要となります。
/tls	セッションの暗号化に start-TLS の使用を強制し、それをサポートしていないサーバとの接続を拒否します。
/notls	たとえサーバがそれをサポートしていたとしても、セッションで start-TLS による暗号化を使用しません。
/readonly	読み込み専用でのメールボックスのオープンを要求します（IMAP のみ。 NNTP では無視され、SMTP および POP3 ではエラーとなります）。

username

ユーザ名。

password

username のパスワード。

options

options はビットマスクであり、以下の組み合わせとなります。

OP_READONLY - メールボックスを読み込み専用でオープンします。
OP_ANONYMOUS - news に関して .newsrc を使用せず、更新もしません（NNTP のみ）。
OP_HALFOPEN - IMAP 及び NNTP 名について、接続をオープンしますがメールボックスはオープンしません。
CL_EXPUNGE - メールボックスを閉じる際に、自動的にメールボックスを削除します（imap_delete() および imap_expunge() も参照ください）。
OP_DEBUG - プロトコルネゴシエーションをデバッグします。
OP_SHORTCACHE - 短い（elt-only）キャッシングを行います。
OP_SILENT - イベントを受信しません（内部で使用します）。
OP_PROTOTYPE - ドライバのプロトタイプを返します。
OP_SECURE - セキュアでない認証を行いません。

n_retries

接続試行の最大数。

params

接続パラメータ。次の (文字列の) キーを使って接続パラメータを設定することができます。

DISABLE_AUTHENTICATOR - 認証プロパティを無効にする

返り値

成功した場合は IMAP ストリームを、失敗した場合は FALSE を返します。

変更履歴

バージョン	説明
5.3.2	`params` が追加されました。
5.2.0	`n_retries` が追加されました。

Since Version 5.3.2 there's a 6th parameter available to disable authentication with GSSAPI or NTLM:



Example:

<?php

$mbox = imap_open("{w2010ExchangeServer:993/imap/ssl}", $user, $password, NULL, 1, array('DISABLE_AUTHENTICATOR' => 'GSSAPI'));

?>



This solves the problem with Exchange 2010 for me. As a reference see https://bugs.php.net/bug.php?id=33500

If your connection is too slow, try it with port and without domain.





<?php


//Normal connection


$mailbox = imap_open("{SERVER}INBOX", $username, $password);





//Faster connection


$mailbox = imap_open("{SERVER:143}INBOX", $username, $password);





//Very slow connection


$mailbox = imap_open ("{SERVER.DOMAIN}INBOX", "DOMAIN/".$username, $password);


?>

I managed to use this function against Exchange 2010 without recompiling to disable kerberos



It's important to me that php installs per the standard package (yum install php)



Exchange 2010 triggers kerberos in php, and you require the kinit thing (search around google for "imap_open kinit exchange 2010" and you will find this)



To get it working I had to:

1. setup the krb5.conf file correctly

2. do a kinit username@DOMAIN.DOM with a valid username / password

3. rename the ticket file to reflect the user id of apache (usually 48)

   /tmp/krb5cc_48

4. fix ownership

   chown apache.apache /tmp/krb5cc_48



but the exchange server will use the kerberos ticket and not the username password - unless you use ssl



<?php



    $imap_user = "username";

    $imap_pass = "password";

    $imap_server = "{w2010kExchangeServer:993/novalidate-cert/ssl}";



    $mbox = imap_open("{$imap_server}INBOX", $imap_user, $imap_pass);



    $sorted_mbox = imap_sort($mbox, SORTDATE, 0);

    $totalrows = imap_num_msg($mbox);

    print "$imap_server\n";



    $startvalue = 0;

    while ($startvalue < $totalrows) {



        $headers = imap_fetchheader($mbox, $sorted_mbox[ $startvalue ] );

        $subject = array();

        preg_match_all('/^Subject: (.*)/m', $headers, $subject);

        print $subject[1][0] . "\n";



        $startvalue++;

    }

?>

    

One small step for php / exchange, one Giant leap for David  ....

For those having issues with Gmail (my problem was : "too many login failures" on a webserver, but no problem on localhost..), instead of opening with :



$inbox = imap_open($hostname,$username,$password,NULL,1) or die('Cannot connect to Gmail: ' . imap_last_error());



Use :



$inbox = imap_open($hostname,$username,$password,NULL,1) or die('Cannot connect to Gmail: ' . print_r(imap_errors()));



You will be able to see the full list of errors that happened, and hopefully it will guide you to an answer.

In my case, Google wanted me to unlock my account by typing in a captcha. But this error wasn't clearly shown through imap_last_error().



Cheers,

Using: 


<?php


imap_open( "{server.example.com:143}INBOX" , 'login' , 'password' );


?>





Got this error:


"Couldn't open stream {server.example.com:143}INBOX" 





Solved by adding the flag "novalidate-cert":


<?php


imap_open( "{server.example.com:143/novalidate-cert}INBOX" , 'login' , 'password' );


?>

"Couldn't open stream {127.0.0.1:143/imap/notls}INBOX" 



Solved by only replacing 127.0.0.1 with localhost, php and IMAP server both in same machine, not through Proxy or anything. Weird!

if u ever get something like this:

Make sure your PHP is enabled with imap via the phpinfo() function



'--with-imap-dir=/opt/lampp' '--with-imap-ssl' '--with-imap=/opt/lampp'



and 



IMAP c-Client Version 2007e

SSL Support Yes



I noticed that my apache script was working but my cli script was not. Turns out my php cli executable didn't have imap setup so I had to use another php cli executable.

kay at rrr dot de 01-Feb-2010 02:46


imap_open is very simple to use, but struggles a litte bit on setups with ssl and tls.



this are tested examples for different hosts and protocols.



uncomment the host/protocol line and fill in correct username and password.

My script kept on timing out, even though the syntax was spot on... ultimately, I figured out that the port was blocked by my webhost, where I ran this on a shared server...



I post this just in case you miss this obvious, like I did.

To open an email message (*.eml) stored on disk you should add at the start of the message the following line:



From dummy@localhost  Sat Jan  1 00:00:00 1970



Then with imap_open("path/file.eml","","") you can process the email message as usal

Jason Pires 26-Apr-2008 03:26


Dears.

In my case, e-mail host was the IMAP enabled.

So, just use the imap_open as the very simple form like:



$mailbox = "{mail.myhost.com:143/notls}INBOX";

$user = "me@myhost.com"; 

$pass = "mypassword"; 



$connection = imap_open($mailbox,$user,$pass) or die(imap_last_error()."<br>Connection Faliure!");



thanks!

I was trying imap_open() function but I was continuously getting this error:



Array ( [0] => [CLOSED] IMAP connection broken (server response) )



I was finally able to solve this problem (which is a very common problem as I saw it on the net but could not find any solution to it) so I'm posting my solution here which I hope will be useful to others.



I used stunnel program (http://www.stunnel.org/) and made changes in the stunnel.conf file as follows:



I added these lines:

[imapsClient]

accept = localhost:143

connect  = imapserver:993

client = yes

sslVersion = TLSv1



This will map insecure imap connection from localhost:143 to imapserver:993 (IMAP with SSL).



After this I tried this code and it worked fine:



<?php



$user="";

$pass="";

$imap = @imap_open("{localhost:143}INBOX", $user, $pass);

?>



and I was able to do away with the errors.

Works with Gmail's new IMAP function for personal and for Google Apps.



$mbox = imap_open ("{imap.gmail.com:993/imap/ssl}INBOX", "username@gmail.com", "password")

     or die("can't connect: " . imap_last_error());

askalski at synacor dot com 28-Sep-2007 01:20


By default, imap_open() will retry an incorrect password 3 times before giving up.  This is a feature built into the c-client library intended for interactive mail clients (which can prompt the end user for a new username/password combo.)



The new optional parameter "$n_retries" allows PHP to override the default retry limit.  There is absolutely no reason to leave this at default, or to set it to any value other than 1.  This is especially important if the mail server you're using locks users out after too many login failures.

Setting a mailbox name (eg INBOX) at the end of the connection string does not work when using imap_open() with OP_HALFOPEN. You may use imap_reopen() then.



<?php



/* this will fail : */

$connection = imap_open('{mx.example.net}INBOX', 'foo', 'secret', OP_HALFOPEN.);

$num_mgs = imap_num_msg($connection);

imap_close($connection);



/* this will do : */

$connection = imap_open('{mx.example.net}INBOX', 'foo', 'secret', OP_HALFOPEN.);

imap_reopen($connection, '{mx.example.net}INBOX');

$num_mgs = imap_num_msg($connection);

imap_close($connection);



?>

Beginning with 5.2.2, binaries built for Windows also seem to have changed its default behavior.

'/notls' needs to be specified for a non-SSL connection.

Fladnag 27-Feb-2007 07:38


you can avoid this message :



Warning: (null)(); Mailbox is empty (errflg=1) in Unknown on line 0



by specified the option OP_SILENT to imap_open.

Amit 12-Sep-2006 02:55


None of the above comments explain the configuration issues on Apache/Windows combination. I thought it might be helpful to list my findings here so that Windows people's time is saved.



There is a bug in Windows php_imap.dll that prevents it from connecting it to the SSL IMAP/POP3 server.

shaikh_zaid at yahoo dot com 05-Apr-2006 04:25


imap_open will not open a stream if your server operates with Transport Layer Security (i.e. TLS) imap_open connects with SSL if its there. So try opening mailbox as 



$mailbox="{mail.domain.com:143/imap/notls}"; 

or

$mailbox="{mail.domain.com:110/pop3/notls}"; This works...



Some mail server requires you to provide username@domain.com so you can always use. user@doamin.com



$conn=imap_open($mailbox, $username, $password);



Some server may ask for username as "user=user@domain.com"

Looking for a cool PHP Script to help you connect to a POP3 server, and download E-Mail to MySQL? Check out my neet-skeet script I wrote. Have fun.



Http://www.sellchain.com/phPOP3/phPOP3.txt



Download the above TXT file, and rename it to phPOP3.php.



Trust me, you will learn mostly everything about IMAP with this script.



By the way, be sure to use print_r($headers) to discover the headers that come with each message. You can setup your MySQL + Email Account information at the top of the script. No includes required!



Enjoyz;)

when i was getting my folders...

a little tip for those who get really frustrated even after reading all the right solutions and implementing them but still get the same errors or none at all..:

after having changed the code.. restart the httpd deamon..



for Fedora or any other Red Hat Linux OS (/etc/init.d/httpd restart).



After this you will be able to make a imap/pop3 stream from apache..

I can connect to my email server with no problem using regular usernames and passwords but.... in my server the usernames are long.. like name.surname1.surname2@subdomain.domain.com , and i get an error when the username size is over 40 chars:



$conn = imap_open("{". $server . ":110/pop3}", $username, $user_password) or die ("Failed with error: ".imap_last_error());



returns



Too many login failures



when the username is over 40 chars. Just remember that if you plan to use long usernames.

thanks to the one who added that the login part should be the whole email address for it to work.. (assuming of course that all other stuff is good and working ;)



to add something, in the 'email address' login name, is not really the email address, ,it's the pop login name plus '@' plus the domain.. hope it's not confusing... 



poploginname@domain.com



not



emailaddress@domain.com..

To authenticate using kerberos V / GSSAPI, you might need to add "user=" to the connection string.. eg:



$mbox = imap_open( "\{imap.example.com:143/imap/notls/user=" . $user . "}INBOX", $user, $passwd );



Our IMAP servers won't allow a user other than the user specified in the kerberos credentials connect using those credentials unless you specify that extra "user=" in the connection string.  Passing it as an argument to imap_open() doesn't seem to be enough.

In order to make a IMAP connection to a Microsoft Exchange Server 5.5, I used this connection-string :



<?php

if(imap_open ("{192.168.1.6:143/imap}Inbox", "DOMAIN/USERNAME/ALIAS", "PASSWORD"))

{

    echo 'Connection success!';

}

else

{

    echo 'Connection failed';

}

?>



By replacing "Inbox" with, e.g. "Tasks", its possible to see all your tasks. I Hope this helps anybody!

Thanks for all your comments.  The user comments have saved me countless times.



I'd like to give back in my small way by providing this little tip.  To test your pop or imap services you can use telnet (almost all operating systems should come with a command line telnet client).



Here's the pop3 example (the lines that start with + are the server's response):



    telnet your.pop.host.com 110

    +OK POP3 your.pop.host.com v2001.78 server ready

    user your_username

    +OK User name accepted, password please

    pass your_password

    +OK Mailbox open, 23 messages



Note that your pop server may be on some other port than 110 but that is the default/standard.



Here's the imap example (Lines that have OK near the begining are server responses):



    telnet your.imap.host.com 143

    * OK [CAPABILITY IMAP4REV1...]

    1 LOGIN "your_username" "your_password"

    1 OK [CAPABILITY...] ... User your_username authenticated



This might be old news to some people but I hope it's helpful for many.

I only run imap on port 993 (ssl only) and I was unable to use imap_open().. couldn't even get an error out of the script, it just sat there and timed out with no messages in the logs or anything--the page wouldn't load.



Anyway, this is what finally worked, which I found in the readme for a popular opensource webmail system:



$i = @imap_open("{localhost:993/ssl/novalidate-cert}INBOX", $user, $pw);



I didn't see the 'ssl' option mentioned anywhere in these comments so maybe this will help someone out.

Kyle Putnam 15-Jun-2003 09:22


I was getting bizzare errors that I couldn't find documentation about anywhere on Google. I tried connecting to another server and got different, but just as unusual error messages. I even checked the POP3 server logs and it said something about invalid command... I figured it was another libc problem.



Stupidly enough, the problem was that I was using an unset variable for the password! Make sure you don't have an empty username or password... you'll have a hard time debugging the problem ;)

Had problems to use imap_open with iMail 6.06 Server. My problem was (sounds stupid): Didn't realise that the username had to be the full email address and not just the login. Maybe this helps some people.

"notls" seems to be required for PHP on RedHat 8.0, but it seems that "/norsh" is also advisable; without it, the client library will attempt an RSH connection and wait for this to timeout before reverting to normal IMAP. This was causing a 15 second delay in imap_open for me. Looking at the client lib C code this will likely be an issue on other platforms as well as they update to the newer version. You can use both "/notls" and "/norsh", e.g. the first parameter to imap_open can be something like: "{your.imap.host/imap/notls/norsh}".

I had been having lots of trouble trying to get imap_open to connect to an imap server.  Then I found another post online that suggested this and it worked, so I am going to post it here.  I hope this helps others..



"I have tried with the following strings instead and it works: 



for pop3: {www.server.com:110/pop3/notls}INBOX 



and for imap: {www.server.com:143/notls}INBOX.

pop3 seems to like refusing connection if you have OP_READONLY set



testers: be forewarned :P

hi

  Note for all having problems to connect hosts using imap_open:



  I spent almost week trying to fix my script which was connecting to localhost but was unable to connect any other host. Sollution was actually wery simple but I'm writing that note becouse there are some posts at usenet or forums decribing similiar problems. And actually I haven't found any  answer for that. So for all of you trying to connect to hosts with imap_open CHECK IF THERE IS NO FIREWALL BLOCKING POP3.

Note about "PHP Warning:  Certificate failure"



I'm not sure if this is a RedHat, PHP, or IMAP library issue, but the default for SSL seems to have changed.



You now need to specify "/notls" when you don't want TLS, rather than only needing to specify "/ssl" when you do.



Example:  



"{localhost:143}INBOX"



becomes:



"{localhost:143/notls}INBOX"

I ran into the 

PHP Warning:  Certificate failure for <server>: self signed certificate:

message while upgrading 4.0.6->4.1.2.  I'm pleased to report that {<server>:<port>/imap/tls/novalidate-cert}<mailbox>

works as expected (and fixes my problem).  I'm using IMP 2.2.8.

Hi,

I just want to say to all redhat people who have problem (Couldn't open stream) with the connection on the local pop server to use this :

{127.0.0.1:110/pop3/notls}INBOX

hope this help

For all imap functions where you specify the mailbox string it is important that you ALWAYS use IP (not hostname) and the portnumber. If you do not do this imap functions will be painfully slow.

Using hostname instead of IP adds 3 seconds to each IMAP call, not using portnumber adds 10 seconds to each imap call. (hint: use gethostbyname() )

brojann at netscape dot com 31-Oct-2001 08:31


You can do





<? $foo = imap_errors(); ?>





to clear unwanted warning messages like 'Mailbox is empty'

It would be nice to mention that this function does send headers. It makes sense, but it is not obvious. It took me a while to figure it out. I authenticate against a POP3 server, and set a cookie if the authentication validates. At least I wanted to :) But since it sends a header to the server, setcookie() won't work.

I have found that the syntax for the imap_open command in PHP 4 differs whether you're passing a variable to the imap_open function or declaring the host directly within the function.  If you are passing variables to the imap_open function, the syntax should look like:





$username = "user";


$password = "password";


$mailserver = "mail.somedomina.com:110/imap";





$link = imap_open("\{$mailserver}INBOX",$username,$password);





If you don't include the leading backslash (\) you will not open the stream.  Likewise you cannot pass the curly braces to the function.





If you define the server directly, omit the leading backslash.





$username = "user";


$password = "password";





$link = imap_open("{mail.somedomain.com:110/pop3}",$username,$password)"





I discovered all of this after 3 days of trying to get all of this work on redhat 7.1.

A better way to connect to a mail server would be to use uri syntax, for example:





imap://username:password@server.com:143/INBOX/message/part





this is very easy to parse using 'parse_url()'





Remember to keep your username and password hidden if your over an open network

IMAP, POP and NNTP are ok. But plaintext mailboxes are unmentioned here. You just forget the {part} and go for the file (tested on unix): 





$mbox = imap_open ($a_mail_box_file_name_in_home_dir, "", "") || die("Snif...:


".imap_last_error());

Connections to the IMAP server work without specifying the port number, but they are slow, so specifying the port number is important if you don't want a slow application.

I have a single comment to add about imap_open.


If you want to connect to a news server, without specifying any news gruop, you can use the following:





<?php


$server = "{news.servername.com/nntp:119}";


$nntp = imap_open($server,"","",OP_HALFOPEN);


?>





and $nntp will become the connection ID.
