If you use cron, sendmail processes can build-up due to network or DNS failures or large mail queues or a combination. Believe me, you do NOT want to run sendmail from cron. Second, running sendmail -q30m or -bd or in any manner at all without first setting it up isn't going to work very well... if you enable sendmail by default, without any real setup, it will not have access to the entire internet due to the strict rules checking that occurs on many SMTP servers these days. Before you can run sendmail on a platform you need to do one of two things: (A) setup a smarthost or (B) make sure the machine's hostname, forward, AND reverse DNS is setup 100% properly. One mistake and a good bit of the internet will bounce your email. Generally speaking, when you throw a rackmount box onto the net the chances of sendmail being able to deliver to all destinations directly from that box are close to nil due to the hostname and/or DNS not being properly setup. On the machines I setup at BEST and at Backplane, every box smarthosts sendmail except one. So there isn't much point running sendmail by default (-bd and/or -qNm) unless the installation procedure asks for a smarthost. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
