Question help need it... issue with dns

I spent the entire weekend trying to solve this and yet still working on it!!!

I just got my server from fedex
moved everything from old to new with Centos 5.1

ok here is an idea of what I have..

DSL line come in to my modem from modem goes to my router,
my router forwards traffict to my main server
apache Worked!!!
all domains that I host works OK
DNS is running at which is my main server...
on my other server is my Email server Running postfix
on my router is set to forward smtp/POP
well, I can not reaching my email server with any client email softwares..

my dns is only has master since I think my router will direct traffict to those ports...

or am I wrong :-0 ?

on my /etc/hosts. localhost.localdomain localhost ns2
::1 localhost6.localdomain6 localhost6

on my /etc/resolv.conf

; generated by /sbin/dhclient-script
search # Router gateway
nameserver # main server

with this setup seems to works fine excepts my email server...

and Honestly I never done any other setup where I run many services from different machine, I always done it withing one single system and since
I want take some of the load from the old server I decited to other new one and got stuck on email srver....

hope you guys can help me...

What POP server are you using?

Also, since you said DSL: is this business-class DSL? If not, most ISPs block the SMTP port at their firewall.

Finally, do note that with a NAT setup, you cannot use a client behind the NAT to connect to a server that is port-forwarded through the NAT. You'd have to connect to it's internal address.
