Postfixadmin is a great interface for virtual domains and virtual users administration for postfix.... instead of phpmyadmin which is a full blown database administration interface.. a bit of a overkill...

Installation and configuration of squirrelmail would also be a plus to have a really complete mail server tutorial.

And there is squirrelmail-postfixadmin to allow users changing their password, vacation message and forwards through squirrelmail interface.

Would it be possible to integrate this three extras in the tutorial.... I think it would make it more complete and a "real"and complete mail server tutorial.

Either way thanks for the great tutorial.
