[Oberon] SMTP tunneled through SSH

[Easthope]

Folk,

In SSH.Tool Guenter Feldmann gives this example.

  SSH.StartForwarding  fld at relayhost  1025:mailhost:25   ~

According to the specification, locPort = 1025.

Yet the Mail.Panel sends mail by SMTP which uses port 25.
So can anyone tell me why locPort = 1025?

Thanks,                    ... Peter E.
