[Dovecot] Dovecot alias and mailbox problem

Hi All,

My Postfix / Dovecot / MySQL is running fine but I have the following issue:

When I create the following mailboxes test@example.com and test1@example.com it is working fine. I can create an alias test2@examples.com => test1@example.com that is also working without a problem, only when I create test@example.com => test1@example.com email is only delivered to test1@.... instead to both test@.... and test1@....

I believe it is properly just a setting but please help me out here !

Let me know if you need any more information before I post configs etc.

Best regards,

Jeroen
