  It probably has to do with your resolv.conf file. Make sure it has a
"domain" line. In addition, by invoking sendmail with the -bt flag and
also the -d0-99.4 flag, you get to see exactly what queries are being
made to your name server. I did this once, and saw things like 
host.ucar.edu.ucar.edu (double domain sickness). Another thing you can do
is to fire up named with debugging. This will probably tell you what is
really happening.
  Another thing is that if you compile sendmail 5.61 without NO_WILDCARD_MX
defined, the only queries that ever seem to be made are for CNAMES. Of
course, if you do define NO_WILDCARD_MX, then you had better not have
a wildcard MX record for your domain, or every single query will succeed
even when it is bogus.
