Hi Christian,

We run a mailman hosting service and none of our clients have any issues in
delivery. I suggest the first issue that may be causing the delay is your
messages are being queued instead of being delivered right away. On a
cPanel/Exim server, a high server load can cause messages to be queued. Also
Exim comes with some pre-set settings that can cause a busy mailman list's
messages to be queued:


Once a message is queued, there will be a delay in delivery as a result. The
settings we have come up with due to our past experience in Mailman hosting
has served our clients (and us!) very well.
