The information is a bit outdated. Also I don't agree with the "DNSBLs are bad" recommendation (we're blocking over 50% of the mail using DNSBLs here). > My original email asked if anyone else was seeing this... not so much > as "what can I do about it". I've been using sendmail for about 11yrs now. I just did some stats, I'm seeing about 80 disconnects per minute due to command timeout... out of about 6000 simultaneous sendmail connections outstanding. I used to have the command timeout at 10 minutes, so that meant 800 wasted sendmail processes (about 13%) so I reduced it to 2 minutes (your peers have the option to use that timeout to cache outgoing sendmail connections. It's polite to leave it at the maximum recommended MCI_CACHE_TIMEOUT, which is 10 minutes. (But in over 80% of the cases you'd be polite to spammers...) -- Jan-Pieter Cornet <[EMAIL PROTECTED]> !!
