Hi,
We have recently upgraded from Mailman 2 to Mailman 3. Since then I have observed many user reports that mails to mailing lists don't reach all members. My suspicion is that there are too many "dead" members on those lists. This was not a problem on Mailman 2, but has become a problem on Mailman 3. It seems to me that for example Mailman 3 sends mails to the first 5 existing member addresses from domain A, then encounters several (20 or so seems to be the threshold) "dead" member addresses from domain A that generate a bounce and then does not even attempt to reach the remaining 800 member adresses from domain A and only sends to members on domain B and domain C.
Is there a way to globaly ignore bounces and send out mails to all members of a list, no matter what?
Thanks, Julian
