In general, sendmail works for me. I am able to send and receive email to external email addresses from my local machine. I've noticed strange errors in the logs though.

In /System/Library/StartupItems/Sendmail/Sendmail, the following lines open two instances of sendmail:

/usr/sbin/sendmail -bd -q1h
/usr/sbin/sendmail -C /etc/mail/ -q1h

What is the purpose of the second one. I noticed that the 1st one runs as root and the second one runs as smmsp. What's the significance of this?

Also, I keep getting an hourly error in CrashReporter. It used to dump the error in the console.log, but I created the file with the correct permissions in the CrashReport directory. It appears to do with the -q1h settings above since something happens each 1 hour.

I cannot seem to find any info on the thread 'dns_is_local_name'. Is this causing the problem? If so, what's the fix? Is it related to the following mail.log error:
