Interesting... I also manage the mail servers, we use postfix with Amavid, ClamAV and Spamassassian. I know this is a mailman list but, is that (SMTP_MAX_RCPTS = 500) a postfix mail server configuration?

In addition to the above, check Mailman's smtp-failure log if you can. The 450 number (and exactly how can he know that?) suggests that possibly list delivery was chunked with the default SMTP_MAX_RCPTS = 500 and only one chunk was accepted by the MTA. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
