Thx a lot for the additional info on the permissions, it eventually worked for that specific user(firstname.lastname@example.org). However I'm a little bit puzzled, do you have to manually create the maildir folder for every user manually? I've tried creating a new user using phpmyadmin site as stated in the howto however that did not create the folder in /home/vmail/mydomain/.. . I tried sending an initial email however that did not help either. There has to be a method for this folders to be created automatically once u create the user. I mean that would be the elegant way or am I absurd?
