[Mailman-Users] Fwd: Mailman error.

2020-08-25 Thread Soporte Syscomed via Mailman-Users
Good morning. 
 

Today, when I tried to access Mailman, I obtained the following error:

 

---
 

 

Bug in Mailman version  

We're sorry, we hit a bug! 

Please inform the webmaster for this site of this problem. Printing of 
traceback and other system information has been explicitly inhibited, but the 
webmaster can find this information in the Mailman error logs.

I have checked the logs and they have no information.

 

I have checked mailman status and it's active and also have checked the 
permissions and they're right.

 

It still doesn't work and I have no idea of what to do.

 Can you help me please? Thank you.

The ` ` indication says that

from Mailman.mm_cfg import VERSION

threw an exception. This is most likely due to some change made to
Mailman/mm_cfg.py (or possibly Mailman/Defaults.py although you should
never change that) that created a Python syntax error.

Try as the Mailman user to cd to the Mailman directory and do

  python -c 'import mm_cfg'

That should give you more information as to the actual problem.

[Mailman-Users] google/gmail issues

2020-08-25 Thread Jeffrey Westgate
We run a list of our mailman listserver that our public school sysadmins use to 
share info.  The problem is - a lot of them have become Google schools, and 
Google has a problem with list servers.

Each post winds up going to multiple Google mail domains, and they bounce:

 stat=Deferred: 451-4.3.0 Multiple destination domains per transaction is 
unsupported.

meaning the emails are queued, sometimes for quite a while, as the system sends 
each domain, one attempt (and one mess of deferrals) at a time.

Is there a setting I can change or add that would allow mailman to kind of 
bundle each domain, open a thread, and send one-thread-per-domain or 
one-domain-per-thread to alleviate the issue?

We are a bit behind, using Mailman version: 2.1.20

If you are sending to multiple recipients in one transaction, they are
grouped by TLD but not by sub-domain within TLD. You need to tell
Mailman to send one recipient per transaction. You can set

SMTP_MAX_RCPTS = 1

in mm_cfg.py, but if you're going to do that there is no downside to
enabling VERP for better bounce recognition with the setting

VERP_DELIVERY_INTERVAL = 1

That setting is sufficient to VERP all messages which ensures each SMTP
transaction has only one recipient.
