How to change ISPCONFIG email address

[mnzava]

Hello guys,
I am trying to change the email address to have a meaningful look.
My web address is www.example.com and i addred roundcubemail package through update in ISPConfig.
Now when i create email account it looks like this staff@www.example.com

Where can i change it so that it looks like staff@example.com?

Can anyone tell me what to add to postfix configuration so that my server can send emails directly to another server next to it(within LAN) without using the public ip?

Thanx and regards,
Mnzava

If you have downloaded the latest RoundCube package provided here: http://www.ispconfig.org/downloads/r...il-0.1-rc2.pkg you should not have the problem with www, because the package contains a patch to solve this:

The line 782 within /home/admispconfig/ispconfig/web/roundcubemail//program/include/main.inc has been changed from:

782 $line = trim($line);

to:

782 $line = trim(str_replace("www.", "", $line));
