Hi, I have a Zarafa server that uses Postfix for local delivery. I want it to send e-mail (sent do one specific domain) to a second server as last-resort backup (there already are nightly backups). I have the second Postfix server already setup to consider itself the target for the domain in question. It delivers in one catch-all box with X-Original-To and Delivered-To headers, so that I can use fetchmail to read the messages and redeliver to the Delivered-To.
What's left, is having the primary deliver to it's mailbox_transport AND forward to that second server. Postfix delivers mail to Zarafa like: mailbox_transport = zarafa: zarafa_destination_recipient_limit = 1 virtual_alias_maps = mysql:/etc/postfix/mysql-aliases.cf The mailbox transport (as defined in master.cf) is a tool that accepts data on stdin to deliver into Zarafa's store (mysql + file based). Virtual_alias_maps is an SQL command which basically returns the j.doe in j....@example.com, but only for existing users. In other words, it retrieves the Zarafa username from the e-mail address. >From master.cf: zarafa unix - n n - 10 pipe flags= user=vmail argv=/usr/bin/zarafa-dagent ${user} How do I setup Postfix so that it sends all incoming mail (for one domain only) to that zarafa transport as well as forward to another server?
