I have been able to successfully send a mail to my list members, who are stored in a MySQL, database. This worked when there were eight members. Now that I'm trying it on a production level with approx. 200 members it doesn't work...or, at least, it hasn't after the first 45 min.
SMTP_MAX_RCPTS = 500
There are currently only 157 members in my list.
/var/qmail/concurrencyremote is 250
/var/qmail/concurrencylocal is 30
Could anyone help me improve this performance?
Look in Mailman's smtp log for a message like
Feb 04 03:30:05 2009 (12244) <message-id> smtp to LISTNAME for 157 recips, completed in n.nnn seconds
where <message-id> is the message-id of your message and LISTNAME is the name of your list. If that log message is there, mailman has completed delivery to qmail. If n.nnn seconds is excessively long, search the FAQ at <> for performance.
If the entire delay is not explained by n.nnn seconds, the delay is in Qmail's delivery of the mail. If Qmail is delivering directly, this is a Qmail question. If Qmail is relaying via your ISP, your ISP may be throttling delivery.
