Hi,
Comcast/Charter (found out about that one Saturday night when trying to
reply to a legit individual message) both reject the message as soon as
a blocked server connects, you don't even get to say HELO. Microsoft,
when they decide you're evil and put you on their internal blacklist,
reject after Mail from:. I find these rejections quite annoying, because
clearly this means their spam analytics software is missing out on a lot
of details that could help them make a more informed decision about
whether to accept the message.
That's the point of rejecting on HELO: you don't download megabytes of
content and waste CPU cycles trying to make sense of it. It's a
feature-not-a-bug.
