I'm running sendmail on 3 pc under Sco Unix V4.2R3.2.
I've a problem with 1:
I can send mail to others, but when I receive one, it goes on /usr/spool/mqueue.
If I edit this file I can see a line:
MDeferred: Host Name Lookup Failure
What's the problem ?
All others services (ftp, telnet, rcp, ...) run well on this machine.
