I just configured my sendmail to be able to send & receive mail to/from the internet, and it’s working like a champ except for one thing:
Relevant information includes the fact that I’m behind a router, with ports 1 to 110 forwarded to the linux machine. I’m running a dns on that machine, which, obviously, is the primary dns for my domain and network. (originally thought this could be it - that sendmail is doing a gethostbyaddress on itself, until I realized that the linux box has an address of 192.168.1.2, being behind the router and all.) After I post this, I’m going to examine my /etc/hosts and see if that has anything to do with it.
Any ideas on how I can get this to stop?
