Hi, first post to this list but long term Linux user here.
I have Postfix configured for virtual domains and delivery to cyrus-imap
via LMTP over IP. All is working well besides one detail.
It seems that when senders request a DSN they do not get any response.
I've tested this from an external Exchange system and I can see my test
message arriving in the logfiles but no trace of an outgoing DSN.
You need to configure the Postfix LMTP client that it is doing final
delivery (LMTP does not assume that every delivery is final, they
could be to a content filter instead).
Either in master.cf:
lmtp unix .. .. .. .. .. lmtpd flags=DORX
Or in main.cf (obsolescent feature):
lmtp_assume_final = yes
Do "postfix reload" after changing the configuration.
Don't mess with delivery status filters.

Thank you Wietse, much appreciated.
Just checking syntax my master.cf now has these lines
virtual unix - n n - - virtual
lmtp unix - - n - - lmtp flags=DORX
anvil unix - - n - 1 anvil
and main.cf has this line
virtual_transport = lmtp:knetmailfiles.kensnet:2003
where that DNS name resolves locally
and I can see these lines are now being added to the delivered e-mail
headers
Delivered-To: k...@kensnet.org
X-Original-To: k...@kensnet.org
But senders are not getting DSN's
Any thoughts??
Many thanks
Ken
