First, it appears that message delivery from Mailman is slow. There are multiple possible reasons for this. It can be that SMTP delivery from Mailman to the outgoing MTA is slow - see the FAQ at <https://wiki.list.org/x/17892002>. If this is the case, the FAQ has some suggestions for fixing this. It can also be the case that delivery from the outgoing MTA to the various recipient MTAs is being throttled by the recipient MTAs. Examination of the outgoing MTA's logs should reveal this. Also, if people reply-all to posts rather than replying just to the list, the direct recipients will probably get the reply before the other list members. In short, you need access to Mailman's logs and the outgoing MTA's logs in order to diagnose this further. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
