"sgtech" "." "uucp" However, when I send mail to adnan@chubsie I always get: 550 adnan@chubsie... Host unknown A couple of things. Most fundamentally, if sendmail is resolving a host to "chubsie.sgtech.uucp," then your hosts table (not being on the Internet, I assume you use /etc/hosts) must contain an IP entry for that host by exactly that name. Having an entry for just "chubsie" is insufficient within this context; the full name is required. Add it to the relevant line of your hosts table, e.g., 192.193.194.5 chubsie chubsie.sgtech.uucp Somewhat more mundanely...t'ain't no such domain as "sgtech.uucp" in a Real Sense. The top-level domain ".uucp" is a hack instigated vaguely of necessity by the UUCP Project when getting registrations going and when creating smail 2.x. Having hosts within that domain is a bit bizarre at best. You'd do much better to register a real domain and use it for all news/mail-related correspondence. Then you could have (presumably) "chubsie.sgtech.com" in your hosts table, things would look a lot more like the rest of the universe expects it to look, and more of the world would be able (to say nothing of more willing) to correspond with you in the first place.
