Firstly, my thanks to all who commented. Based upon the weight of
this information, I have upgraded my MTA to full 'zen' RBL checking.
However, I would like to point out that there is a class of 'poor'
internet users who want to send mail legitimately directly from
their dynamic IP. These are people who either want to send more mail
than their ISP's outgoing server permits, or wish to avoid
additional fees from their ISP.
Too bad. I will not accept mail from them. I have numerous checks in
place to prevent users on dynamic IPs sending mail to me.
Technically, yes, they are trying to get 'around' the policies of
their ISP. But (by most notewrothy example) if they are outside the
area for DSL service and *must* use the local cable high speed, and
the cable company's pricing policy presumes that any sender of large
volumes of mail simply 'must' be a commercial venture, immediately
doubling the cost of the home internet connection to a 'business'
one, then the operator of a small club mailing list may have no
choice but to try and send their mail directly.
Nope, there are other choices. You can use any mailserver to send your
mail. that's what submission is for. You cannot use your dynamic
connection as a mailserver because if you do, the majority of admins
will assume you are a spammer.
These people are not without 'other solutions'. But they are making
the best of a bad one. Is this enough to warrant down-scoring the PBL?
Not in my opinion. And for me, PBL is not a score, it is a flat-out
blacklist with an instant rejection before the DATA phase of the SMTP
transaction.
I no longer think so. But just so we're clear, just because an ISP
says that they have a 'policy' does not mean we can brush off the
attempts by people to bypass being *stuck* with those ISP's as not
really being 'legitimate'.
There are always exceptions.
No. There are NO circumstances under which it is OK for someone on a
PBL (or non-PBL dynamic) connection to send email DIRECTLY to my
mailserver.
