Horde Failed to connect to localhost:25 error message

By Gunjan · August 6, 2010

On Shared server as well  as on Dedicated server some time we are facing large connection issue to SMTP port 25 at that time mostly we disable SMTP port 25 and enable any other port for SMTP but after changing SMTP port mostly we receive following error message in Horde webmail.

There was an error sending your message: Failed to connect to localhost:25 [SMTP: Invalid response code received from server (code: 421, response: Too many concurrent SMTP connections; please try again later.)]

To resolve above error simply change SMTP port from 25 to new SMTP port  in following file.

root@server [/usr/local/cpanel/base/horde/imp/config]# Pico servers.php

And change following line

From

‘smtpport’ => 25,

To

‘smtpport’ => 26,

We have taken new port as 26 for example you can use any port as per your requirement.

Similar problem with “Squirrelmail” then refer following steps.

root@server [/usr/local/cpanel/base/3rdparty/squirrelmail/config]#pico config_default.php

Change following line

From

$smtpPort = 25;

To

$smtpPort = 26;

Save file and exit and now open the webmail.

As well as RoundCube error logs showing following logs

The error is occur becasue Mysql could not insert the values from UNIXTIME. To avoid this error simply open file

/usr/local/cpanel/base/3rdparty/roundcube/program/include/rcube_mdb2.php and replace following code

From

return “FROM_UNIXTIME($timestamp)”;

To

return sprintf(“FROM_UNIXTIME(%d)”, $timestamp);

Now clear cache from your local machine refresh RoundCube error page.

Horde session issue?

By Gunjan · January 27, 2010



There is a very common  issue where Horde prevents access to webmail by repeatedly redirecting viewers to Language Selection screen. The following commands, executed as root, will solve these issues:

root@server[~]#/usr/local/cpanel/bin/checkperlmodules
root@server[~]#/scripts/fullhordereset
root@server[~]#myisamchk -r /var/lib/mysql/horde/horde_sessionhandler.MYI

If still you have problem then check the ownership for session directory present in /var/cpanel/userhomes/cpanelhorde directory.

root@server[~]#ll /var/cpanel/userhomes/cpanelhorde

drwx–x–x 4 cpanelhorde cpanelhorde 4096 Jun  5  2009 ./
drwx–x–x 7 root        root        4096 Dec 17 01:48 ../
drwxr-x— 2 cpanelhorde cpanelhorde 4096 Jun  5  2009 mail/
drwx—— 2 cpanelhorde cpanelhorde 4096 Jan 27 14:01 sessions/
Session directory should be cpanelhorde.cpanelhorde ownership recursively

Send mail by using phpmail function.

By Gunjan · September 21, 2009

You can create a simple php mail form by using following code..

————————–

<?
$to      = ‘supp0rt@xyz.com’;
$subject = ‘The test for mail function’;
$message = ‘Hello’;
$headers = ‘From: test@abc123.com’ . “\r\n” .
‘Reply-To: test@testforever123.com’ . “\r\n” .
‘X-Mailer: PHP/’ . phpversion();
mail($to, $subject, $message, $headers);
?>

————————–

If you are not able to receive the E-mail then you need to check whether your server is allowing to send an E-mail by using phpmail() or not?’ if you are having root login then check the servers main php.ini file.

root@Gunjan []# php -i | grep php.ini
Configuration File (php.ini) Path => /usr/local/lib
Loaded Configuration File => /usr/local/lib/php.ini

root@Gunjan []# cat /usr/local/lib/php.ini | grep disable_function
disable_functions=”system,passthru,popen,proc_close,proc_get_status,proc_nice,proc_open,proc_terminate,shell_exec,highlight_file,phpmail”

and remove the phpmail() from server mail php.ini file and restart the Apache web server.

Or

If you are not having root login details then contact your hosting provider and ask them to enable the phpmail() for your hosting account.

You can also send me an E-mail at nsk.gunjan@gmail.com if you have any queries…
