If you are using some other MTA, you should configure `mailwrapper' to redirect requests to that MTA rather than executing Sendmail(tm). On modern FreeBSD systems, /usr/sbin/sendmail is actually the `mailwrapper' program, which redirects requests to your MTA of choice. If you are not running any sort of MTA on the machine, then you should generate and install a sendmail.cf file which uses the `nullclient' configuration to send all of its outgoing mail to an appropriate mail server. You should also periodically run a `sendmail -q' in order to deliver any mail which was queued due to the relay host being unreachable. Whether you use `cron' or `sendmail -qINTERVAL' to do this is a matter of religion. -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
