Issue :

Where can I check the current version of Horde webmail client running with cPanel ?

Solution :

If you have ‘root’ SSH access to the server then, simply open the file /var/cpanel/horde/version using your favorite editor and you’ll be able to see the current Horde version.

Issue :

The following error occurs while trying to login to any webmail client :

Internal Server Error
Unable to load featurelist ‘default’: Permission denied

Fix :

1. Log in to the server via SSH as ‘root’.
2. Open the file /etc/cpupdate.conf and make sure CPANEL=manual.
3. Run /scripts/upcp –force

This should fix the issue!

Issue :

All email accounts were accessible via the main email account for that domain but now they aren’t.

Fix :

E-mail access from the main account to individual e-mail accounts is provided by symbolic links (symlinks) within the cPanel user account’s mail directory which link to the directory of each individual e-mail account. To restore or re-create these, use the following built-in cPanel script :

/scripts/linksubemailtomainacct

Issue :

How to check and open the emails in all email accounts on a domain ?
PS. It is a cPanel/WHM server.

Solution :

This can be achieved in the following way :

- Login to Horde as the cPanel user (not as a webmail user).
- Go to the Mail section of Horde.
- Click on the drop-down where you see INBOX and you’ll see other POP3/IMAP accounts listed there.

Issue :

While trying to send email, following error occurs in Horde/Squirrelmail :
535 Incorrect authentication data

Fix:

This usually occurs when the option “Allow mail account authentication using the password of the domain owner’s account” in WHM -> Server Configuration -> Tweak Settings is enabled.
Webmail logs you in but attempts to use the cPanel account password via SMTP. Hence. the problem.

Disable the option and check.
If this does not fix the issue then try running /scripts/upcp

Issue :

When an user logs into webmail , he should just have one email client ( say roundcube ) whereas all other users should see all the three.

Solution :

Suppose the username is ‘xyzco’ for the domain xyz.com.

1. SSH into the server as root, and edit the file /var/cpanel/users/xyzco

2. Now, if you want to disable all webmail applications and enable roundcube mail, you would need to add following lines:

skiphorde=1
skipsqmail=1
skiprcmail=0

You can specify the values as per your requirement.

3. Then run the following command :

/scripts/updateuserdomains

4. And restart cPanel :

/etc/init.d/cpanel restart

Now, when the user xyzco logs into webmail, he will only see roundcube mail, and not the other two

Issue :

Horde webmail screen of a domain is displaying a blank screen.

Cause :

May be due to recent PHP upgrade. You may find the following entries in error log (/etc/httpd/logs/error_log)

================

PHP 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

=================

Fix :

Edit /etc/httpd/conf.d/zz010_psa_httpd.conf
Replace all occurance of
php_admin_value include_path “/usr/share/psa-horde:/usr/share/psa-horde/pear:.”
to
php_admin_value include_path “/usr/share/psa-horde/lib:/usr/share/psa-horde:/usr/share/psa-horde/pear:.”

Restart Apache
