Virtual Alias Translation to User Mailbox Not Passed to Dovecot LDA

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, abuse@mydomain.tld is resolved to
myuser@mydomain.com, but the recipient that the dovecot LDA receives is
abuse@mydomain.com rather than myuser@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,
