How much time? They should appear almost immediately in qfiles/out/
unless they've been spending time in qfiles/retry/.

What is in Mailman's smtp-failure log? What does Mailman's smtp log
look like? does it show the symptom of a backlogged qfiles/out/ queue?
Namely, many successive entries being timestamped at intervals equal
to the processing time of the entry.

What 'debug=1'? If you mean you just set


in SMTPDirect.py, this will do nothing. The only additional debugging
switch that applies to SMTPDirect.py is described at
and be sure to note that this won't work and will only cause
additional problems if your Python version is less than 2.4.

If the messages that aren't being delivered are remaining in Mailman's
qfiles/retry and qfiles/out queues, report what you find in Mailman's
smtp-failure (and as Brad suggested, error) logs and what you find
from examination of Mailman's smtp log.

If the messages are accepted by sendmail and then fail to be delivered,
that part at least is a sendmail issue.
