Yes, we will *never* see legitimate mail from a PBL-listed IP.
See, it all comes down to what you think 'legitimate' is.
The recipient wants the e-mail. DUH.
That's not my definition at all; it's not even the definition of any
mailadmin I've ever met. We reject mail users *want* all the time.
It's our job.
A common, simple definition, and in terms of warning people about
the imperfections of *any* blocklist, it is the one that MATTERS.
Nope, sometimes people WANT email that is laden down with malware,
viruses, executable files, web bugs, or other things that compromise
the security of not just themselves, but of others. Just because the
recipient WANTS it does not make it legitimate. Users also WANT to
send 50MB (or 3GB) attachments via email.
This does not mean you have a bad policy. Nor does it mean that the
people breaking
their ISP's policy necessarily deserve to be given special treatment.
It means only that you are misleading people to make them think that
they will never have *wanted* mail blocked by PBL.
*wanted* mail is blocked all the time. What I say is that once a mail
is received by the server, it is never discarded; before I accept it
though, I will reject all sorts of mail for all sorts of reasons.
People are free to get their emil elsewhere. Most people find that
'elsewhere' means hundreds of more spam messages every single day. I
had one domain that was briefly hosted somewhere else. Their incoming
mail jumped from ~200 messages a day to nearly 2,000 messages a day.
They were completely overwhelmed with the mass of spam to the point
that their Outlook Database on their windows machines was overwhelmed
and corrupted itself. They lost all their email over the last three
years.
Fortunately for them, I had not deleted the maildirs off my server's
backups, so they were able to move their domain back and recover
almost all their mail.
It has already happened. Will happen again. It is no different than
some poor schmuck setting up their hosting and discovering they are
in a spam-infested IP block. Doesn't mean their mail is 'not
legitimate' because our policy agrees with spamhaus and blocks that
whole range.
Again, you have a differing opinion of legitimate than I do.
I don't care. It's the *meaning* that matters. Not the *word*.
Fine, then, the meaning. Your meaning is *wanted* and my meaning is
mail from a verifiable source with a verifiable (fixed) IP, correct
rDNS that is authorized to send mail and does not appear in the zen
RBL. It also has to helo with a legitimate hostname and the rDNS
cannot contain strings like 'pool' or 'dynamic' or 'dialup'.
