Urgent: Aliases and Mailboxes issue

[Anonymous]

Dear,

    I have used postfixadmin 2.3.1 before and everything work fine with Postfix virtual support, recently I have upgrade to postfixadmin 2.3.3 version but face a critical issue in aliases setting

   In past for an alias address I need to create a physical one, let say, sales@demo.local, and then add aliases sales@demo.local to re-forward to specific users

  however, in postfixadmin 2.3.3 it seems fail as it will pop up error message saying that an email address already exists, no matter in create alias or mailbox task. Now, I have try enable alias option in config.inc.php and edit alias option in mailboxes setting, however a return email receive with unknown user issue. I guess it is because no object in mailbox but in alias, how can I fix it ?

   thanks

Regards,
Lawes

Your text is slightly confusing, therefore I'll try to summarize your problem first:

You have an alias sales@demo.local, and now you want to change it to a mailbox. Correct?

If yes: delete the alias, then create a mailbox with the same address.

If this doesn't match your problem, please describe your problem exactly, and also tell me if sales@demo.local exists in the alias and/or mailbox table.
