Tunneling SMTP Traffic Via SSH Question

Hi,
        My apologies if this is a dumb question -- I'm attempting to 
forward port 25 (SMTP) over SSH via Putty to an off-campus mail server. 
Here are my connection parameters:

Session> Hostname (for SSH): mail.myserver.com          Port: 22
SSH > Preferred SSH protocol version: 2
Tunnels> Forwarded ports: localhost port 3225 to Destination 
mail.myserver.com:25

When I try testing the connection in Outlook it returns an error saying 
that Outlook cannot connect to the server. I know that out our outbound 
WAN connection is blocking outbound port 25 traffic and I was hoping that 
I could get around that via SSH forwarding. Firewalls can't peer into the 
tunneled packet headers, can they? Help! 

Cheers,
DTS
