tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 3276/master and postfix is up and running
Check this tip:
in main.cf
inet_interfaces = all
then restart postfix
/etc/init.d/postfix restart
Note: reload will not be enough you must restart like the command above
then
nmap 127.0.0.1
you should get 25/tcp
then nmap your.local.ip.address
nmap 192.168.0.10 for example
you should get 25/tcp
Now login to your postfix server and
telnet 127.0.0.1 25
you should get in
Now from another machine
telnet 192.168.0.10 (assuming this is your ip)
you should also get in
Good Luck

Since your postfix is running I'll suggest you to logon to your console and try :
- to telnet your localhost
telnet localhost 25
Does it respond?
- If it does try to telnet your IP address:
telnet IP.address.of.server 25
Does it respond (I mena from the console)
- If it does did you check the IPTables Firewall if SMTP (port 25) is allowed ?
Will you post the output of your /etc/sysconfig/iptables ?
- to telnet your localhost
telnet localhost 25

ASKER
is it iptables -nL for the output?
ASKER
also what is the best flavor of Linux to use for this app?
Iptables -nL output is so comples. /etc/sysconfig/iptables is the source of it.. Post either of you want here.
I believe the best flavor for serving an aplicaiton is aServer unix platform such as RedHAT, Debian etc. If you don't want to pay for support I'll suggest CentOS.
