Using mutt to send an email to eleph...@a.known.domain elicits no NDR, while doing the same directly via SMTP does, when I manually set the NOTIFY parameter. I have procmail verbosely logging everything that fetchmail delivers, and there's nothing coming back when I use mutt.
Why do I need that? My posts to another list disappear silently, unless I poke them through the SMTP pipe by hand. Maybe if I were properly set up for DSN, I might receive a clue to the black hole, because the list host does show "250 DSN" in response to an ehlo. I have: $ mutt -v Mutt 1.5.20 (2009-06-14) ... SENDMAIL="/usr/sbin/sendmail" Ah, do I have to recompile mutt, with "-N failure,delay" there, in order for the following mutt settings to work? [1]: set dsn_notify="failure,delay" dsn_return=hdrs The following postfix config didn't help: $ postconf sendmail_path sendmail_path = /usr/sbin/sendmail -N failure,delay $ postconf mail_version mail_version = 2.7.0 # My postfix version. [1] My googling thus far suggests that it "should oughta" work as is, because postfix's sendmail default implies limited -N: "The built-in default corresponds with "delay,failure"." according to: http://www.postfix.org/DSN_README.html Does anyone have this working? Erik -- Arrgh. I just found a Google search result of somebody who was experiencing exactly the same problem as me, only to find it was me :-(. - Read on luv-talk ML.
