thank you guys for all your help. I have resolved the incoming mail problem. It was due to the recursive problem meaning i made the email of name@visualx.net to send to name@visualx.net. That was the problem. Now my only problem is sending mail. Mail will not go outbound. Does anyone know how to solve this? Once again, thanks for all your help.

are you sure you have a 'gateway' setup on your mail server?

make sure your gateway is set to your router, aka your firewall to the internet.

run sendmail from the commandline on your server. ie - sendmail your @email.com ....then hit enter, type some stuff, then end a line with a .

if this works, there is something with your email clients, etc.
if it does not, then something on the server..

either way, the best thing to do here, is check your log files, they speak the world about what is happening.
so, look in /var/log/maillog, and see what is happening with that mail....it may be possible that your /etc/resolv.conf is not setup correctly (DNS nameservers), or, your hostname/domainname is not setup correctly....other MTA's require that this stuff be setup properly.

ok i fixed the outbound. it was because the destination ip wasnt listed so i had to add it. Another question is that sendmail is running really slow. It takes about 15 seconds to connect to get my mail from outlook.
