That is vague and really not true.
Why do you think that? Your ability to find out why a specific domain
got on a blacklist is pretty close to zero. You may be able to look at
every single email being send from the domain, you might be able to
verify that there's nothing bad there (no spambots, etc), but you can't
find out what message got the domain on the blacklist. You can't even
validate that the message which caused the block passed the SPF checks
and was actually sent from infrastructure controlled by the domain in
question. Once upon a time you could actually get that kind of
information but those days are long gone.
However as a person I depend on e-mail and I really never had any of
these issues.
How would you know? Honest question. Unless you get a reply to every
mail you send, you can't actually know whether every mail was recieved.
I look at how these heuristic based filter work and it is easy to
maintain a form of communication where the likelihood of blocked
is low.
Pretty much don't do anything marketers do.
Do not use binary content.
Do not use HTML
No links either
Avoid explicit words.
I could go on.
So if you do that and end up on a blacklist, what's your next step?
So, a Debian contributor Alice sends a private e-mail to a Debian
contributor Bob. Both Alice and Bob use arbitrary e-mail servers, most
likely beyond their control. E-mail bounces, Alice does not get any
meaningful diagnostics, Bob does not get a e-mail. It can happen.
It can happen, you could win the lottery :)
Could, Would, if and but. All vague forms of arguing.
It does happen, whether you want to accept it or not. Either your
assessment of the odds are wrong or I want to find out where you play
the lottery.
