First of all, your question is a Qmail question, not a Mailman question.

recips, completed in ttt.ttt seconds

In Mailman's 'smtp' log, Mailman has finished delivery of all messages
to Qmail. If there were any issues with delivery from Mailman to Qmail,
they will be logged in Mailman's 'smtp-failure' log.

Again, this is a Qmail question. What I suspect you're seeing is a
result of Mailman delivering non-VERPed, non-personalized messages in
chunks of up to SMTP_MAX_RCPTS recipients per SMTP transaction and Qmail
experiencing retryable errors on some of the recipients in the chunk and
delivering others.

But ask someone who knows Qmail if you want a definitive answer.
