This problem seems to hit a lot of mailing lists. It could be a problem
with Mailman (which most use), but I doubt it. I think it is just the
way mail gets sent around the internet.
All sensible systems will use UNIX and sendmail
or a simpler equivalent. I know sendmail checks for mail to send at some
regular interval - 15 minutes on my system.
I don't understand how mail circulates, but it is quite possible that
one machine copies it to another, which then copies it to a third, with
each machine doing this every 15 minutes.
Since there is no reproducible path a message will take from one
computer to another, and the time period starts when the system is
booted and not set via a time server, it probably explains why messages
arrive out of order.
I'm not an IT expert, but my explanation is probably not too far off.
I don't think it is anything the list manager could do anything about.
