I'm trying to activate sieve. In all tutorials I have seen I need to set dovecot_destination_recipient_limit = 1 in Postfix's main.cf. Can anyone explain why ? I like to know because when I set this and the dovecot transport in Postfix, I'm having problems when aliasses are used that map to different recipients, i.e. info@... results in user1@..., user2@..., etc. The problems are an error from Postfix : Oct 30 09:25:19 lace3 postfix/pipe[19729]: 8A77E2D5B5B: to=some.body@some.where.org, relay=dovecot, delay=2390, delays=2390/0.04/0/0.01, dsn=4.3.5, status=deferred (mail system configuration error) Oct 30 09:25:19 lace3 postfix/pipe[19729]: warning: pipe flag `D' requires dovecot_destination_recipient_limit = 1
Well, the last message says it all: you've instructed postifx' pipe to add a "Delivered-To" header field to the message. And this obviously can't work when delivering one message to multiple recipients in one pass. See also: http://www.postfix.org/pipe.8.html
