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,

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.

I don't have direct experience with cPanel, but there are a number of
hosting services that provide Mailman via cPanel, and as far as I know,
this is not a systemic problem.

As I tried to indicate in my earlier reply at
,
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.
