What is in the logs. In particular, the entire 'bounce' log from 11/1
thru 11/24.

Do you mean admin_notify_mchanges is No, bounce_notify_owner_on_removal
is No or something else. When cron/disabled removes a member, it always
tries to notify the member. There's no setting for that.

Was cron/disabled running between 11/15 and 11/24?

Were changes made to the list's bounce settings after 11/1. In
particular, the number of notices (bounce_you_are_disabled_warnings) is
set in the user's bounce info when deliverry is first disabled and
subsequent changes to the list setting won't affect the number of
notices for that user.

Also what's in the subscribe log on 11/24. Where the 'unrelated'
unsubscribes all done at the time cron/disabled ran (default 09:00)?

[Mailman-Users] subscribers being unsubscribed at wrong time based on bounce settings.

2016-11-30 Thread Christopher Adams 
Hello,

I have done some fairly extensive examination of logs and list settings for
one of the lists hosted here, and I can't come up with a sensible
explanation to tell a customer.

The list is set to not send messages when a person unsubscribes.

The bounce settings are set so that 2 warning messages are sent after the
address is disabled and those messages should be 7 days apart.

A message was sent to the list on 11/1. I see in the logs that a
substantial number of addresses reached the bounce limit and were disabled.
So, based on the bounce settings, many of these should have been
unsubscribed 14 days later. They were not.

However, on 11/24, there was a mass unsubscribe of addresses that had been
disabled. Additionally, many (including some that turned out to have valid
addresses) received unsubscribe notices.

I tend to think that these are not related, but are two issues that I have
not been able to explain.

Many thanks,

Christopher Adams

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.

[Mailman-Users] Time needed to deliver list messages

2016-11-30 Thread Christian F Buser via Mailman-Users 
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
