is dovecot knowing all alias addresses ?, with dovecot-lda its done in 
postfix before delivering to dovecot-lda, so if the recipient here is a 
valid mailbox it should work, but i think dovecot needs alias support to 
be used same way as postfix does

when it works it would be a dream, seems we are not there yet
