Using Custom Vhost Entries for Webmail, MySQL, Etc.

[TGates]

You can NOT use 'mail.domain.com' since this is reserved for your actual mail server connections! Delete it from sub domains.

You did not read the tutorial completely.

You do NOT create webmail.domain.com sub domain in the sub domain manager. (In your case mail.domain.com)
From tutorial:

Code:

(NOTE: Do NOT add these sub-domains in the sub-domain module!)

Your custom vhost entries are not correct:

Code:

</virtualHost>
# Configuration for WebMail
<VirtualHost *:80>
   ServerAdmin mail@domain.tld
   DocumentRoot "/etc/sentora/panel/etc/apps/webmail/"
   

#php_admin_value

open_basedir "/etc/sentora/panel/etc/apps/webmail:/var/sentora/temp/"
   php_admin_value suhosin.executor.func.blacklist "passthru, show_source, shell_exec, system, pcntl_exec, popen, pclose, proc_open, proc_nice, proc_terminate, proc_get_status, proc_close, leak, apache_child_terminate, posix_kill, posix_mkfifo, posix_setpgid, posix_setsid, posix_setuid, escapeshellcmd, escapeshellarg, exec"
   ServerName mail.domain.com
   AddType application/x-httpd-php .php3 .php
   <Directory />
       Options FollowSymLinks Indexes
       AllowOverride All
       Order Allow,Deny
       Allow from all
   </Directory>

As per the tutorial, it should be:

Code:

</VirtualHost>

   # Configuration for WebMail - webmail.yoursite.tld
   <VirtualHost *:80>
   ServerAdmin webmaster[at]yoursite.tld
       DocumentRoot "/etc/sentora/panel/etc/apps/webmail/"
       ServerName webmail.yoursite.tld
   AddType application/x-httpd-php .php3 .php
       <Directory />
       Options FollowSymLinks Indexes
       AllowOverride All
       Order Allow,Deny
       Allow from all
       </Directory>

Also in the tutorial:

Code:

You will also need to add them in your DNS registrar and in Sentora's DNS Manager module
(add A records webmail.yoursite.tld)
