Getting HTTP 404 error message when accessing webmail on any domain

For windows plesk 🙂

If you are receiving HTTP 404 error when accessing webmail.domain.com, try to execute the following to resolve the issue.

+++++++++
“%plesk_bin%\websrvmng.exe” –reconfigure-webmail
“%plesk_bin%\defpackagemng.exe” –fix –type=webmail.horde
+++++++++

This error means that the web site ‘webmail (default)’, responsible for webmail is not configured correctly in IIS. The above specified command need to be launched to fix the problem:

Trying to retrieve the URL: server_hostname:11444

Sometime you may receive the following error message while trying to access the plesk “https://IP:8443”.

********
This webpage is not available.

or

The webpage at https://server_hostname:11444 might be temporarily down.

or

ERROR The requested URL could not be retrieved. While trying to retrieve the URL: server_hostname:11444
*********

This issue mainly happening when you upgrade plesk to 9.X version.

You can try following fix from your end.

*******
1. Login to the server through SSH.
2. Execute the following command to disable SSO.
/usr/local/psa/bin/sso –disable
*******

Most of the case the above fix will resolve the issue. 🙂

Webmail is showing blank page.

Problem: In plesk, sometime, after php upgrade if you take “http://webmail.domian.com” via browser, you will get blank page.

Check the apache logs. If you find any logs as follows:

—
Fatal error: require_once() [function.require]: Failed opening required ‘Horde/String.php’ (include_path=’/usr/share/psa-horde:/usr/share/psa-horde/pear:.’) in /usr/share/psa-horde/lib/Horde/Browser.php on line 4
—

Perform following steps:

—

1. Copy Webmail VirtualHost entry from “/etc/httpd/conf.d/zz010_psa_httpd.conf” to “/etc/httpd/conf.d/webmail.conf”.

2. Find the “php_admin_value include_path” value from the “/etc/httpd/conf.d/webmail.conf” file.

3. Replace it with following entry:

php_admin_value include_path “/usr/share/psa-horde/lib:/usr/share/psa-horde:/usr/share/psa-horde/pear:.

Note : You should change this value for all “php_admin_value include_path”.

4. Restart apache and plesk services.

Now, access the URL “http://webmail.domian.com” 🙂
