Looks like the email verification application at verifier.port25.com described 
in this 
(https://urldefense.com/v3/__https://postmarkapp.com/blog/port25s-authentication-and-spam-assassin-tool__;!!C08knRND!PrBldtpRgxKKiM4s5iOopr5tvdArMkaT0NOcLZ5y6IKC6PJJcOuDRnWhb9D7-ogPprQ6xVSHmU422booi3A$
 ) article may have been shut down.

Anyone have any insight into this or alternative tools for testing DKIM, SPF, 
and similar in one go?

I wonder if this guy would teach me his secret to get AWS to unblock port 25 
for him. They turned me down, as I'm sort of a security risk, being an elite 
hax0r with xnnd.com and all that, haxing port 25s all over town.
(And maybe I don't WANT to use SES, yuck.)

Re: [mailop] Email.it issues

Hi,

I just reviewed our logs and we are delivering normally to email.it. I don’t 
see any current or recent issues delivering to email.it either.

Cheers,
Andrew

Good day,

We have been unable to successfully deliver any messages to email.it 
[email.it]
 in IT  for the past week and have been unable to get any response from their 
abuse email.

Main errors received suggest  "No valid hosts" with all emails  bouncing back.

Has anyone experienced the same or have a contact I could reach out to?



Kind regards

Well, I would disagree with that, actually. Much of this is automated on the 
recipient end at large receivers, and if it so happens that messages from a 
certain large ESP that contain a certain header are only half as likely to be 
manually flagged as spam as other messages from that ESP, that would be likely 
to show up in a bayesian/AI classification system.

In general, it's in the interest of senders to provide *any* clues they can 
that certain messages they send are more likely to be legitimate. It doesn't 
need to be a header; a large ESP signing COI messages with a different DKIM 
selector would be a similar clue that could be used.
Differentiation of mail stream types helps everyone.

Even on the human side, it seems people spend vast amounts of time looking for 
clues about mail they can use to filter it -- I've seen people trying to guess 
whether certain ESP mail is COI or not based on the sending IP address ranges. 
If people are willing to do things like that, I think they'd be willing to use 
any other clues reputable senders provide.

But I may be wrong.


>I will also say there is such a thing as spam to a COI address.

Yes, definitely. Doing such a thing would be unhelpful to the sender, because 
it would make systems trust the "clue" from that sender less than they 
otherwise would.

I can't recall the exact quote but a key rule is basically this;

And thus you are training Google's AI to treat completely legit (only
misdirected) messages as spam.
Maybe one day these senders will find out that when they send another message 
(this time to the correct address), it will end up in the recipient's spam 
folder, without them knowing why.
Don't do it to them. Just delete those messages, don't put them to spam.
