Hi,

I have a problem with my installation of postfix and virtual aliases (mysql). When an email is sent to a virtual alias, the smtp subsystem translates the alias to the correct real mailbox. However, when the dovecot/pipe subsystem is called, the recipient is the alias and NOT the real mailbox. For instance, ab...@mydomain.tld is resolved to myu...@mydomain.com, but the recipient that the dovecot LDA receives is ab...@mydomain.com rather than myu...@mydomain.com, and since dovecot's SQL does query users from the 'alias' table only the 'users' table, thus the message is bounced.

I have tried all that I can think of to resolve this, but to no avail...

Any help gratefully received.

Kind regards,
