Sounds like DNS to me.  Even if sendmail is configured to accept 
unresolvable domains, it's going to sit there a long time waiting.  What 
does:

nslookup `hostname`

return?  I'm not sure if sendmail uses /etc/hosts but try adding the 
output of hostname to /etc/hosts on the same line as "127.0.0.1 
localhost localhost.localdomain"
