What's in Mailman's 'smtp' log? I.e. in the <message-id> smtp to listname for nnnn recips, completed ... entries is nnnn the expected number? If it is, this is not a Mailman issue per se. It is an MTA/mail delivery issue. Also, if Mailman is chunking recipients (delivering to the MTA with more that one recipient per transaction), the MTA may also be delivering to recipient MXs with more than one recipient per transaction so one 'status=sent' might be a delivery for more than one recipient. See the post at <https://mail.python.org/pipermail/mailman-users/2017-March/081959.html> for some insight on this. > I also looked at this from the perspective of one ISP -- gmail.com. > > [root@ray06 email]# cat /var/log/maillog.processed /var/log/maillog | grep > 'Mar 9' | grep status=sent | grep gmail.com | wc > 976 18544 254501 > [root@ray06 email]# sudo /usr/lib/mailman/bin/list_members english-devotion > | grep gmail.com | wc > 4945 4945 110190 > > The maillogs show 976 gmail.com emails sent while one of our lists has > 4,945 gmail.com members. Again it appears that only some members are > receiving email. Counts of "missing" messages indicate that there is a problem but give no clue as to what the problem might be. What are a few of the status log messages for the ones that weren't status=sent? Are they 'bounced' or 'deferred' and what is the server's response?. If the migration involved a new IP, large ISPs that are suddenly receiving lots of mail from a previously unknown IP may be applying throttling or greylisting. -- Mark Sapiro <[email protected]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
