Everyone, Thought I could solve this problem, but Looks like I need some help. I am trying to replace our R.H 8.0 internal e-mail server with a faster machine using FC3. I set a FC3 unit up as a desktop PC in order to do the setup and testing before I put it into production. I have set up other machines using sendmail with only the usual problems, but this one has me stumped. The internal mail server 'mailin.domain.com' needs to pass its e-mail to our external server 'mailout.domain.com' while at the same time processing mailin needs to process local mail. define(`SMART_HOST',`mailp.pomec.net')dnl The HUB feature was commented because I want it to process some local mail dnl define(`MAIL_HUB', `mailp.pomec.com')dnl Both of the below are commented out dnl FEATURE(`accept_unresolvable_domains')dnl dnl # dnl FEATURE(`relay_based_on_MX')dnl I was using the mail coomand in the form of mail -s 'test trasnmissions to mailout' Name@xxxxxxxxxxx < ./textfile The maillog on mailin demonstrate that mailout refused the connection. I checked my host, host.allow files, turned off iptables on both units, and still no solution. I decided to watch what was happening using ethereal, and found that sendmail was doing a dns lookup for domain.com and found the internet IP address for mailout.domain.com. Of course when sendmail uses this address it fails a connection which is related to our firewall. I tried using the internal IP address with 'telnet mailout.domain.com 25' and it connects easily. 'telnet "external IP address" 25' does not connect and this is what sendmail is doing. I tried changing the name of of mailout.domain.com in the host file of mailin to something like mailoutp.domain.com but sendmail continues to do DNS searches on 'domain.com' giving it the external IP address that fails. I need sendmail on the new mailin server to stop doing dns searches for the IP address and just use the host file for the internal IP address. I think that would solve this problem. I am sure there is a simple solution, but so far I can not find it. Your help would sure be appreciated. Thanks, Greg Ennis -- Gregory P. Ennis <PoMec@xxxxxxxxx>
