mailman unsubscribing people

[Barb Wunderlich]

CRITICAL!!!!
Today 2/10/12) at 3:10 p.m. CST, the mailman software started unsubscribing people to our mailing list - PURRS1 mailing list. They receive a message from <email address hidden> and are then deleted from the mailing list. Beofre this we had over 2000 addresses in our mailing list, now we are down to 776.
 I contacted LunarPages.Com who hosts our website, but they said we need to contact you about this problem. Please help ASAP.

The members were almost certainly unsubscribed by Mailman's bounce processing. Your hosting provider can review Mailman's 'bounce' log to verify this and can examine the logs of the outgoing MTA to possibly find out more.

You can review your list's bounce processing settings for appropriateness and ensure that all the owner notifications are turned on so that you will receive notification when a member's delivery is disabled by bounce and before the member is removed.

Without additional information to indicate that this is actually a bug and not a result of normal bounce processing, I can only assume that this is not a bug.

Hi.

We think it was bounceprocessing but there is an errror in it..all those emails did not bounce back..reading down it appears that lunarpages says we hit some quota that may have caused the error..we are switching to constant contact once this is fixed. Please note the following email string and the two attachments and see if this helps.Thanks. Barb -----Original Message-----

Here's another email string.
Also, we'd like to know if mailman has a backup of our email subscription list from Thursday 2/9/12 or earlier before any of this occurred. We would want to have it restored as we think we lost around 1700 emails.

Thanks.
Barb

All of the reports in comment #2 appear to be legitimate bounces. The first 14 addresses in the notice in comment #3 also appear to be legitimate. The remaining "Domain purrsnaperville.org has exceeded the max emails per hour (400) allowed. Message discarded." messages indeed appear to be the result of a quota on outgoing mail from your domain imposed by your hosting provider. This is not a Mailman issue. Mailman has been told the address was undeliverable, so Mailman treats it as a bounce.

The problem is your hosting service apparently can't support a mailman list with more than about 400 subscribers and can't support even that many if there is more than one post in an hour. This probably means it won't support anything that generates mail to more than 400 recipients in an hour.

This is something you will have to discuss with your hosting provider. There is little that Mailman can do about it. See the FAQ at <http://wiki.list.org/x/j4A9>. There is a patch attached to that FAQ which implements throttling, but installation of that patch would have to be done by the hosting provider.

Regarding backups, only the hosting provider can tell you if they made any backups and if they still have them. They would need to restore Mailman's lists/purrs1/config.pck file from an appropriate backup.
