You can use user IDs with moer than 8 characters, I guess there is a maximum length, but I don't know what it is. Your problem is most likely that dots are invalid characters for a user ID. You could simply use underscores instead. The dot in the email address in the form of first.last@xxxxxxxxxx is usually done using alias or virtualuser features of the mailserver application.
