Each mail client has a different way of specifying what mail server to use. The
key is to configure your mail client to talk to your local machine.
For instance, in Eudora, you would:
- Go to the Special->Settings...-><Hosts Panel>
- Set it like this:
POP account: [<username>@localhost]
SMTP server: [localhost]
Please see your mail client's documentation for more details. If your SSH
connection is up, you should be able to send and receive mail securely.
