I hsot severall domains on the server and now I noticed that for a particular domain (zice.ro) I only created 2 users, one is the admin the other one is a user. when the user sends an email I see username@mymaindomain instead of @zice.ro... I am using squirrelmail for testing. I changed his emailaddress (sender info) to email@example.com inside squirrelmail but it keeps changing back... why does it always revert back to firstname.lastname@example.org which is my main domain? any clues? what more info would you need?
