My first guess is they are outgoing messages that have encountered some
'retryable' SMTP error on one or more recipients and are being retried.
Normally, they would only be retried every 15 minutes, but possibly this
is occurring more often for some reason.
Are there entries in qfiles/retry?
What is logged in Mailman's smtp-failure log?
What does Mailman's bin/dumpdb show on the .pck (or maybe .bak - need a
-p option for that) files in qfiles/out and qfiles/retry? Look
particularly at the second object from dumpdb - bin/show-qfiles doesn't
What does the MTA say about these?
