Every minute, I thought it was supposed to give up after the second 
attempt?

Anyway, newish versions of sendmail want a fully qualified domain name 
for the machine it is running on. To shut the message up, give the 
machine a name like atmb1.mydomain.com as an alias in the /etc/hosts 
file (or name resolver of choice, but leave it in the /etc/hosts as 
well, just in case there isn't any DNS when it boots).

NOTE -- unless you require a full sendmail setup where folks can SMTP 
mail to your machine from other machines you might want to look at not 
running it as a daemon, but just flushing the mail queue every 30 
minutes or so from cron. There are tutorials out there that explain the 
details.
