You might already know about this, but postforward is good for doing SRS for specific addresses but there is static config (in /etc/aliases) so it's only good for setups that don't change much (unless you automate config updates). postsrsd wants to rewrite everything, even local delivery, but postforward can limit it to just things that get sent to remote servers. cheers, raf _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
