This is expected. It's not written until the message is sent.

Mailman's 'out' queue is backlogged. (I really need to write a FAQ on
You can tell because of the above and there will be several files in
Mailman's qfiles/out directory and the entries in Mailman's 'smtp' log
will be continuous, i.e. the timestamps of each entry will be x seconds
after the previous one where x is the "completed in n.nnn seconds" value.

Multiple, sliced OutgoingRunner processes might help, but the real issue
is it takes too long for Mailman to deliver to Postfix due to Postfix
configuration. In my production installation with full VERP, Mailman
delivers to about 20 or more recipients per second.
See <https://wiki.list.org/x/4030636>, although a lot of that is
outdated, but do note all the stuff on disable_dns_lookups.
