AFAIK, it is actually trying to work out where to deliver email: it is
using the DNS servers to try to work out the final destination for the email.
This behaviour is likely to be because of the usage of sendmail as a mail
gateway, though of course you yourself are not using it as such.
All you need to do (I think) is to make sure that in your /etc/nsswitch.conf
file you have the hosts line as dns first and then files. Hence:
hosts: dns files
networks: files
Thus if your dns servers are down then your computer will fall back on the
files, in which case all you probably need is an entry or two in /etc/hosts
with a localhost entry and your hostname entry.
Personally I use postfix but the configuration is very similar to sendmail.
I could of course be very wrong here!
