Hi all
Our lists run on a cPanel installation of Mailman (cPanel version 60.0.25, Mailman version 2.1.23). Messages sent to the list take some long time to be delivered to the subscribers - in the best case it is about 10 minutes, but it can take up to over 40 minutes.
We asked our provider about it, and he tried to finetune some settings on the server - so far without success. He said he also contacted cPanel support and their response was "this is normal - there is nothing they can do about it", he said.
My question to all who run Mailman on cPanel: Is it true? Are you also experiencing delivery delays?
Thank you, Christian

As I tried to indicate in my earlier reply at <https://mail.python.org/pipermail/mailman-users/2016-November/081539.html>, this is an Exim issue. I'm certain that the Exim configuration on the host server can be tuned so this is not a problem. If your hosting provider is unable or unwilling to do this, you should investigate other hosting services.
Also, please see the next to last paragraph in my earlier reply for specific information about what the host can do.

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:
smtp_accept_queue_per_connection queue_only_load
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.

Once the email is handed off to the MTA, this -is- normal. Email delivery is almost never immediate; some lists I'm on take hours to deliver to everyone; depends on the server load and any extra processing at both ends.
(On one specific list I read at two mailboxes, a message will appear in the first within a minute of sending but will take ten minutes to appear in the other.)
Later,
z!
