I would really keep those requirements at the MTA level using aliasing and whatnot. Delivering a message to multiple folders within a single maildir (duplication) can be one using sieve. > Additionally sieve can not call > external programms. Wrong. http://wiki2.dovecot.org/Pigeonhole/Sieve lists several (albeit experimental) extensions that can run external programs. Setup is not as easy as with procmail (sorry, no maildrop experience here) but it gives the administrator control over what disasters can be triggered when email triggers execution of external tools set up by users. > >> Also consider using amavisd-new + clamav + spamassassin to REJECT >> mails.
