Hello,
I want a special host to be contacted directly and not via a SMTP-resolver host.
I decalred the host in /etc/hosts and added it to sendmail.cf . The hosts name is ipt.rwth-aachen.de. But it is always contaced via the unknown address resolver. So, what must I do to tell sendmail to do a "telnet ipt.rwth-aachen.de 25" and not to send it to the unknown dadress resolver ? Thanks for help!
fhg.de is my unknown address resolver
