Now, let's address the issue of webmail.example.com vs. example.com/webmail.
For those who wish to access SquirrelMail at example.com/webmail, it is necessary to add the following to Apache's configuration:
Code:
Alias /webmail /usr/share/squirrelmail
The above snippet should be added to the "
Apache Directives" field in Sites -> Website -> example.com -> Options [tab].
