Squirrelmail reply email address is wrong

[LazyEyes]

Hey guys,

Starting to use the Squirrelmail webmail interface and found out after composing a new message and sending it out, the recipient sees the wrong reply email. Both the username and domain names are not correct

Example
Real Name Lazy
Username web5_lazyeyes
Email lazyeyes [@domain.com]

The reply address shows web5_lazyeyes@domain.com and the domain is the hosting address and not my site's domain.

Checking the /etc/postfix/virtusertable both web5_lazyeyes@domain.com and lazyeyes@domain.com with the alias web5_lazyeyes. And the account receives emails from both email address.

How do i fix the reply email problems, help guys. Thanks!
