dovecot lda bouncing postfix aliases

[Tom Hendrikx]

Hi,

Typically, postfix should resolve the aliases into user accounts that
dovecot knows before you even start delivering to dovecot. You probably
messed something up in the postfix config that disables alias expansion
before dovecot delivery is attempted.

Can you show us your postfix config?

Kind regards,

	Tom
