Hi Mark

Thanks for the emails.

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

Sep 14 11:09:51 2010 (2716) <7FCF6A56F44641DBB64C71FD58C8B186@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

Just wondering if anyone have met with such situation whereby a mailing list have 2000 or more members and it cant send out emails??

I have tried to increase postfix sending recipient (smtpd_recipient_limit and smtpd_recipient_overshoot_limit to 5000 each) , but still cant send out emails.

smtpd_recipient_limit = 5000

smtpd_recipient_overshoot_limit = 5000

Currently I am running mailman version 2.1.9-4.el5 , postfix version 2.3.3-2.1.el5_2 , python version 2.4.3-27.el5.

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

In addition we discovered that in /var/log/mailman/vette , the message is being discardrd by moderate.

Sep 21 17:10:52 2010 (7606) Message discarded by Moderate, msgid: <4C98769D.80406@ntt.com.sg>

This log message does not exist in standard GNU Mailman. What Mailman package/version is this?

Further, this has nothing to do with the message(s) below.

In any case, this appears to be saying that the message was discarded either by a moderator after being held or by the Moderate handler. This has nothing to do with the number of list members.

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

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

The above says that the message was successfully delivered to the outgoing MTA in some number of transactions with a total of 2001 recipients. Mailman has delivered that message. What happens next is up to the MTA.

What are your mm_cfg.py settings if any for SMTP_MAX_RCPTS, SMTPHOST and SMTPPORT? If these are not set in mm_cfg.py, what are the Defaults.py settings?

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

This log is incomplete.

Sep 20 09:34:26 ml2 postfix/local[26043]: AE6251F401: to=<allmember@ml2.ntti.net.sg>, relay=local, delay=0.25, delays=0.11/0/0/0.14, dsn=2.0.0, status=sent (delivered to command: /usr/lib/mailman/mail/mailman post allmember)

The above is the post delivered to Mailman for posting to the allmember list.

Sep 20 09:34:29 ml2 postfix/cleanup[26042]: 4441A1F401: message-id=<mailman.34.1284946467.2713.allmember@ml2.ntti.net.sg> Sep 20 09:34:30 ml2 postfix/cleanup[26042]: 746861F419: message-id=<mailman.34.1284946467.2713.allmember@ml2.ntti.net.sg>

And the above two entries are Mailman generated messages, possibly a notice of a held message to allmember-owner and then the resend of that to the actual owner/moderators.

And a post and two notices as above

Where are the log entries corresponding to the Sep 14 11:09:51 entry in the smtp log? Wher are the rest of the entries for queue ids 4441A1F401, 746861F419, etc?

I appreciate your keeping this thread on the list, but it would help if you would actually join the list too.
