[Mailman-Users] A particular mailing list cant send out emails ifhave 2000 or more members??

[Ricky Lim]

Hi Mark

Thanks for the emails.

In /var/log/mailman/smtp , the log show

Sep 14 11:09:51 2010 (2716) <7FCF6A56F44641DBB64C71FD58C8B186 at jcci19> smtp to allmember for 2001 recips, completed in 2.592 seconds -> (but we are very sure once it hit 2000 or above , it wont send because we are inside the mailing list and didn’t receive the email , but once it is below 2k recipient , we will sure received the email).

In /var/log/mailman/smtp-failure , smtp-failure1 , smtp-failure2 , smtp-failure3 and smtp-failure4 , the log is empty.

The mailog of the postfix will show send "status=sent" irregardless of the numbers of the recipient

What's in Mailman's 'smtp' and 'smtp-failure' logs? What's in the
Postfix log?

Try setting SMTP_MAX_RCPTS to some smallish number, e.g.

SMTP_MAX_RCPTS = 20

in mm_cfg.py
