EMAILS - username.domainname@serverhost.tld ??

Hi there,

I'm just trying to see if there is a way to tidy this up. I managed to implement LDAP for users and groups a while back (following a guide on here) and one thing I have noticed is that when a user logs into serverhost.tld (fictional name) on port 20000 to access usermin, the email address displayed in the top left corner is in the format username.domainname@serverhost.tld.

I would rather that this is username@domainname.tld - as it was before I changed to LDAP.

How do I go about fixing this?

Any help greatly appreciated!

Kind Regards Steven
