I can't use sender_dependent_default_transport_maps because I don't want to use sender-based static "routes". I'm looking for a "random" or round-robin-ish split of smtp that provides consistent "helo .. hostname .. ip .. reverse-dns-lookup" Anyways, I've got the round-robin working now, using transport_maps and this script https://gist.github.com/mvsantos/9813415 But I'm finding the solution very ugly. There must be a more elegant way to do dynamic smtp deliveries... $ postconf mail_version mail_version = 2.11.0 # main.cf transport_maps = tcp:127.0.0.1:9999 # master.cf 127.0.0.1:9999 inet n n n - 0 spawn user=nobody argv=/usr/local/sbin/postfix-smtp-roundrobin.pl smtp1 unix - - n - - smtp -o myhostname=X.mydomain.tld -o smtp_helo_name=X.mydomain.tld -o smtp_bind_address=1.1.1.1 -o syslog_name=smtp-1 smtp2 unix - - n - - smtp -o myhostname=Y.mydomain.tld -o smtp_helo_name=Y.mydomain.tld -o smtp_bind_address=2.2.2.2 -o syslog_name=smtp-2 # End of master.cf And for every mail sent or received I have 8 extra lines in my logs (below, not in the correct order) and the time of processing has increased a bit - not because of the extra logging, but because of the transport_maps. Let's see how it performs under load tomorrow, when I make it live... smtp-roundrobin[1234]: Using: 'smtp2:' transport service. Query: get * smtp-roundrobin[1234]: Using: 'smtp1:' transport service.
