Wietse, thank you, > Postfix local/pipe/virtual delivery agents record the delivered > to address in the Delivered-To: header
Then, in which way would you recommend to copy such a message to special arch...@mydomain mailbox, retaining Delivered-To: header? (and not replacing it with "arch...@mydomain", to allow further sorting) Is it possible to do it with Postfix? I guess this can be done with Dovecot LDA + Sieve, by storing Delivered-To: into some other header and redirecting message to archive mailbox, but that doesnt' seem to be very elegant.
