What does /etc/host.conf have? If it has 'hosts' on the first line,  
how is your /etc/hosts file set on that machine and what is the output  
of 'hostname'? It looks like it might be having trouble resolving it?  
I'm not sure.. I had a similar issue to this a while ago where the  
server would not send mail, after the time out period it would then  
bounce the mail back to itself and manage to send me a copy of the  
original mail saying it couldn't deliver it.. Yet it was able to  
deliver the message saying it couldn't be delivered.. It had something  
to do with the host name resolution after some dns server changes..

Also, if your hostname isn't in the form host.name.com it seems the  
sendmail queue runner will not actually start up.. Which seems to be  
something it does in more recent versions, since I know I'v had  
systems without proper host names in the past and it used to work..  
I'm very behind the times, I only recently moved from 4.x over to 6.2,  
I'v never even used a 5.x version..

I'm really not sure how this magical devfs thing works, except that it  
seems you no longer have to worry about it..

I hope this provides some ideas, sendmail has changed a LOT and I'm  
still working it out.
