No more direct to MX for anything other than a mail server.
What about the MTA I have welded into my MUA?
I'm sure I can figure out a way of welding exim into kmail and have it work...
No matter why reason anyone can come up with that would require a non-
mail server host to need to send on port 25 I say their wrong.
Privacy. I want to send my email from my MUA to a third party using STARTTLS.
Going via an intermediary MTA would compromise that privacy. (PKCS does not
protect headers). I must connect to port 25 because that is where the
third-party MTA is running. Check the standard, that is where a STARTTLS
enabled ESMTP server should be running!
It's time that the US government force all ISP to block any of their
customers from using port 25 unless they request it for their own mail
server. To get that port 25 access they would have to agree that the
ISP could test their server any time they want.
What about foreign ISP's?
For that matter, what abount spammers requesting mail servers for their
US-govt legitimated CAN-SPAM! Ha Ha Ha! You're barking up the wrong
policeman...
This is the only way we are ever going to stop direct to MX spam, the
only way!
So you don't think SPF would work if widely adopted as a standard?
And I say NO. Only customers that run mail servers should ever be
allowed to have use of port 25, period!
Such as spammers?
