files from /var/log/mailman:

error exists and has a few entries but none as recent as Oct 3 which is
the failure date. 

post has this content only:

Oct 01 17:13:04 2018 (2966) post to amsdirectors from
geek at uniserve.com, size=2919,
message-id=<20181001171248.33c61328 at user-Satellite-A100>, success

I can confirm that this was delivered, I received it.

smtp, dated Oct 1 and smtp.1, dated Oct 2, are zero bytes

no file smtp-failure

and from syslog.1 this excerpt at the relevant time:

Oct  3 18:02:11 web5 postfix/smtpd[23732]: connect from
apps-kam-2.gov.bc.ca[] Oct  3 18:02:11 web5
postfix/smtpd[23732]: C21AE8ED2DF:

command: /usr/lib/mailman/mail/mailman post kitimat) Oct  3 18:02:12
web5 postfix/qmgr[1546]: C21AE8ED2DF: removed

so to me this looks just like a normal delivery. I think it must be the
case that mailman handed off the delivery to postfix at this point then
deleted the message. But then why no actual delivery?


In modern fantasy (literary or governmental), killing people is the
usual solution to the so-called war between good and evil. My books are
not conceived in terms of such a war, and offer no simple answers to
simplistic questions.
