  | | | Sendmail failing to resolve IP address of the Smart Host | Sendmail failing to resolve IP address of the Smart Host 2003-12-31 - By Blessing Kamutande
Back Hie All, I have two LAN sites with one site running Exchange 5.5 and this site is the gateway to the Internet. The problem is the other site is running Sendmail 8.12.8 and I defined the Exchange as the smart host name being mailserver, but Sendmail fail to relay mail saying: DEFERRED. Connection time out. Could not resolve host name. I have put mailserver in my /etc/hosts file ad I can ping the exchange server using its name(mailserevr). These servers are on the same net i.e 192.168.1.0
What could be the problem and how can I solve it?
TIA Regards
