In effect, yes. 99.9% of the market is demanding that their mailbox not be
filled up with spam. Most spam has been coming by way of mail amplified by
open relay mail servers. As those servers are gradually getting closed or
blocked, spammers are discovering that with more sophisticated programs (and
there are some people out there selling them these programs) they can get more
mail out by doing it directly to the MX server for the intended recipient.
Many of them do so from a big server on a high speed connection. For them, I
just block them by their name. Others are small operations that continue to
use dialup accounts. If I block them by name, and it would make sense to do
it for the whole set of names for all the dialups since they can dial in as
any one of them, then that affects everyone. Since the usual _practice_ for
99.999% of legitimate mail originating from a dialup is to first inject it into
the dialup ISPs server, then blocking the dialup directly will have no impact
on that legitimate mail.

Why don't you go show them how to fix their mail server?

Send me the price list for the competition, first.

It looks like this is going to be the case, all because of spammers.

You have a dynamic IP address. A spammer may have been using that very
same IP address just a few minutes before you dial in.

If you set things up to receive mail directly, then you will be taking the
very actions that distinquish you from spammers, who generally only send
mail. But as long as you connect to some other POP/IMAP server to pick up
mail, your server won't appear to be something any different than a spammer
would appear.
You need to make yourself look different from a spammer.

Yes, that rule applies. Most spammers are ignorant and are just using a
program they buy. If their mail does not go through, they won't know what
to do about it until the programmer sells them a new program. At that
time we will have to see what it is they are doing then, and find a way
to prevent that mail, if possible.
Keep in mind that if the spammers start to use real domain named servers,
we can block them individually by their names. Some actually do this now
(and I actually cut them off when I get spam from them). If you get your
own domain name (some name within ist.utl.pt perhaps, or register a domain
of your own in .pt or .com) and associate that name with a fixed IP address
you use, then you won't look anonymous. And as long as no spam comes from
a server with that name, I won't be blocking it.
