mail issues

[Rod Rioux]

pic didnt go through

i have a nat box that has server behind it and the servers that are behind

it cant send mail to the mail server on the same network ... internally or

externally.

but i have another firewall that can send email to the mail server it is on

the same external network but the internals are not the same.

I need help for my servers to talk to one another send mail whatever. the

systems ping fine on internal and external between each other.

if i do a "ls -la |sendmail user@mail.server.com it doesnt work. but i can

connect to port 25 on the internal server and manually send mail with

commands. Wierd!

I have sent a pic of a diagram because it is hard to explain... my firewalls

have all external ip bound to them and port forward inside to services on

internal machines. it seems that the servers on the same nat box cannot

connect to another external ip bound on the same nat box. It pings them fine

though. Everywhere else in the world can connect to the machines though!

help me please!
