Close but not quite. Blocking a port is not the real problem. Let me be more explicit. - My server must send outbound email via SMTP. - The mail server that my server must connect to is *not* listening on port 25. It is listening on some other high port, hypothetically 34380 for example. - The mail server that my server must connect to requires that my server authenticate with a user name and password. So I need to tell my sendmail to: - Use port 34380 for outbound SMTP - Use a specific user name and password to authenticate to the server The 'SMART_HOST' setting is appropriate, I think, but I don't see either how to use a specific port or how to specify a user ID and password. > I really like Brennan's Home Server guide for help here (though I don't > use sendmail any longer) > > http://www.brennan.id.au/12-Sendmail_Server.html#encryption This looks like a good resource, thanks.
