Hello Linux Forum readers

I post this thread because i need some help change the apache2
I want to get rid of the annoying name of mail.localhost.com/webmail
I am using Debian with apache2,squirremail and ispconfig3 (followed step by the howtoforge perfect server guide for debian ipsconfig3)

Though there is an issue...my squirrelmail server listens only in mail.localhost.com/webmail

I want to listen to mail.localhost.com,first of all because it's annoying,and secondly because i am having an issue on making work the MX Recods on goddady and i think maybe that's an issue.

If you need more informations about my system please don't hesitate to ask
