That might go away when you disable sendmail. The other log messages Nov 25 03:35:41 foo sendmail[90110]: 2AP2ZeZo090110: to=root, delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=37944, relay=[127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by [127.0.0.1] Nov 25 03:35:41 foo sendmail[90110]: 2AK23ccD044156: to=postmaster, delay=5+00:32:03, xdelay=00:00:00, mailer=relay, pri=487250, relay=[127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by [127.0.0.1] Nov 25 03:35:41 foo sendmail[90110]: 2AK23ccD044156: 2AP2ZeZp090110: return to sender: Cannot send message for 5 days That looks like some local email message, probably one sent by the nightly "periodic" stuff, couldn't be delivered, because no MTA was running on the local computer to receive it. Did you replace sendmail with some other MTA? You pretty much have to run something, so at least local mail (within the computer) will work. A number of things assume they can send email, including the "periodic" stuff and cron. This is all covered in the FreeBSD Handbook, section 29.4, "Changing the Mail Transfer Agent". You should probably read that, and maybe all of chapter 29, "Electronic Mail".
