Looks like it - I keep seeing:

Apr 18 09:07:45 mhrichter sendmail[3376]: My unqualified host name (mhrichter) unknown; sleeping for retry
Apr 18 09:08:45 mhrichter sendmail[3376]: unable to qualify my own domain name (mhrichter) -- using short name

The original host name was something like adsl-69-234-xx-xx-<something>.<an att thing>.com. IIUTC, you're saying I should include that original domain name on the host name line.

The 192.138 address is a local subdomain for the VMWare server NAT (which works really nicely) - would I need to modify that one, too or just the host?
