[Mailman-Users] Messages delivered out of order and delayed

[Veronica Morris]

I run an active discussion group.  Messages come and go from people all
hours of the day.

For the past few months, we've noticed that messages are arriving out of
order, and sometimes are delayed by hours or even a day!

The kicker is that the delivery issues are not the same for everyone.  Some
people will get a particular message immediately, while others will get
that message in an hour, and others in a day.

Most of our users use gmail.

What can we do to fix this?  As ours is a discussion group, timing is
pretty important so that the flow of the conversation isn't interrupted by
people not having read previous messages.

Thank you!
