Re: Any restriction is a service downgrade

They do not need to upgrade to SOHO. They can just use an alternate port. My hosting company provides and alternate port. 1and1 provides an alternate port.

I just don't see why this is an issue. The problem is that port 25 has 2 uses: mail server to server transfer, and mail client to server transfer. Should have been using two different ports from the beginning.

SMTP is much older than any of the client mail protocols (e.g. POP). So, there was never any call for a "client" port in the original specification. SPAM was a fairly non-existent problem when POP was first created, so there still wasn't a compelling reason to add a client-specific port for SMTP trafficing.
