That still wouldn't identify the cause, though. :-( I assume that your ADSL provider uses PPPoE -- how to you fire up your PPP interface at boot? I do this in /etc/rc.conf, which forces ppp to establish a connection before progressing with the boot, which means that the net connection is up by the time sendmail is started: # PPP ppp_enable="YES" ppp_profile="HSE" ppp_mode="ddial" -- Matt Emmerton To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
