MUAs should stop sending email via 25 and use 587 or equivalent instead. There is little actual reason why someone should be able to send TCP/25 SMTP email from a residential connection when most software support authenticated TCP/587 submits. We don't allow most of our residential customer base to speak SMTP TCP/25 to anywhere at all (and we have millions of them). Wish more ISPs would do the same. -- Mikael Abrahamsson email: [email protected]
