Hi There Murat, You added the domain but it seems that it's not your default domain, so you need to send usernames like this: username%domain.com or [EMAIL PROTECTED] instead of just plain username.
A quick solution would be to recompile vpopmail with --enable-default-domain=yourdomain.com Of course that's just guessing, you didn't include a lot of info, so based on what you posted that's my Guess. Good luck! -- Kiril Todorov < -+- > +359 2 9712013 Bulgaria Online < -+- > http://home.online.bg /* waiting... dreaming... wishing... */
