Thanks Ralf, I understand.
Apologies If I did not make myself understandable. I am not sending garbage to
non-existing addresses. All addresses are verified and existing but not all
messages appear to be delivered equally well, to my surprise, while some
servers appear to refuse messages coming from this list for a while, until they
are accepted for distribution, thus delaying overall mailman performance while
it keeps trying to deliver, therefore I was considering to cancel bounce
processing to speed up mailman performance. When I ask my hosting provider for
the SMTP logs there appears to be activity by mailman, bounce processing, when
there are no messages to distribute through the list, therefore I inferred that
we are experiencing delays in distribution, beyond 30-60 minutes, from a
message being sent to a message being distributed, because of this bounce
processing actions. This is a list with about 600 members.
According to your answer this would not work this way.

Dear listers,
I eventually traced that my mailman installation is delaying the
distribution of messages because it is trapped in a bunch of "bounce
processing", dealing with undelivered messages, etc... in this
regard, could I simply inactivate bounce processing?
No. You need to clean out your lists. Why are you sending out garbage to
non-existing addresses at? A properly maintained list has a low
percentage of undeliverables - when (as in your case) the undeliverables
are exceeding the normal fallout of about 3%, then you're having bad
lists.
If I do so I should expect an increase in speed and performance of
mailman and a decrease in delays, but I might risk that some members,
whose messages could not be delivered for whatever reasons, might loose
some of these messages. Is that so?
No.
Would you recommend setting Mailman to not performing bounce processing
to improve its performance? thanks Lluis
No.
Sending mail to non-deliverable adresses is going to get you into
blacklists. That's how Hotmail and SenderScore work. Furthermore
you're going to hit spamtraps sooner or later.
