<DIV>Ok, I'll give my 2 cents too.</DIV>
<DIV> </DIV>
<DIV>If the recommendation that is listed below doesn't work, it may be because your system that is running sendmail doesn't know where to do the lookups.</DIV>
<DIV> </DIV>
<DIV>There are 2 possibilities for why this would be a problem. One, your /etc/resolv.conf on the sendmail machine doesn't point to a name server so that your host name is resolved. If you have a name server listed, the other reason why your sendmail server isn't finding the host is because you aren't looking at a name server to resolve host names in your nsswitch.conf file.</DIV>

<DIV>Between what Clinton mentioned & what I mentioned, you should be able to resolve your issue.</DIV>

<DIV>Happy trails!</DIV>
