Hello I have now tried to form a log file that contains both happy case (500 recipients) and unhappy one (501 recipients)
To debug the case I created 999 bogus users with username us...@listserv.kuntaliitto.fi to user...@listserv.kuntaliitto.fi Because the log file is quite a big one (run with -vvv level of verbosity) I decided to put it to a web server. You can find the log file and the postconf output from: http://appz.kunnat.net/postfix/index.html If you need something further, please ask for it TIA hannu -----Original Message----- From: owner-postfix-us...@postfix.org [mailto:owner-postfix-us...@postfix.org] On Behalf Of Victor Duchovni Sent: 25. helmikuuta 2010 20:09 To: postfix-users@postfix.org Subject: Re: Recipient limit..but where?

Show logging that demonstrates: - Postfix processing a 500 recipient message in a way that you find acceptable. - Postfix processing a 501 recipient message in a way that you find problematic. Show all log entries related to each event, not just smtpd logs, but also related cleanup, qmgr, and delivery agent logs. Post the configuration used at the time the logs were capture along with the logs, restart Postfix prior to the test. -- Viktor. P.S.
