#3 Logged error codes

[Anonymous]

I have a DSL Modem/Router. My email server (a surplus
3COM INternet server, works great even email) is
listening on Port 25. I have fluffy running on a Win2000
box listening on port 26. My DSL router is redirecting
port 25 to port 26 to the IP on the Win2000 box. (You
cannot change listening ports on the 3COM).

Router 192.168.1.1
Fluffy 192.168.1.2 port 26
3COM 192.168.1.4 port 25

I send a test email from my ISP account, this one, which
I have White listed and I get a number 1 in the Deferred
then not received label line.

I am somewhat intelligent but somehow I am missing
what this means and what is happening to the email
sent. I never receive it until and when I turn Fluffy off
and remove the port redirection then the 3COM will pick
up the email from somewhere out in cyberland.

In resetting log level, I see a message of: "<22>Oct 17,
21:15:00 jcits-server Fluffy Open connection

What is state 9 220? Where can I find error codes?

(xxx is an attempt to kep my domain somewhat private.)

Thanks in advance for any assistance.
