No, the aliasing is not the crux of the issue when the resulting recipient is still delivered locally, but see below. > 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. The smtp(8) and lmtp(8) delivery agents do not prepend X-Original-To headers. > and this one: > > http://tech.groups.yahoo.com/group/postfix-users/message/231881 > > "Postfix will not add X-Original-To when forwarding mail." Yes, really when not using a delivery agent that is typically used for outbound or relay email. In the case of lmtp(8) this should perhaps be revisited at some point. > It seems filters were suggested to be used, but it doesn't seem a > common approach.
