The resulting recipient is not delivered locally - it goes to zendesk.com an email 'helpdesk' system. Essentially I have a domain Y.com which points to postfix. Postfix is configure to handle it as a virtual domain with dovecot, but some aliases are set to forward say a...@y.com to zendesk.com. I'm guessing those that get forwarded have nothing to do with local/mailbox delivery agent - and hence its smtp which handles it. > > It seems to make sense from this thread that: > > > > http://www.dovecot.org/list/dovecot/2011-January/056783.html > > > > "postfix adds X-Original-To when delivering to a mailbox > > > > - which delivery via smtp/lmtp isn't.", > > This is right, only the local(8), virtual(8) and pipe(8) (flag-dependent) > prepend X-Original-To.
