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!
