Interesting. Regional effect? After running the incoming address through 
zen.spamhaus which blocks 99% and thus saves me download fees, the 
majority. for me, of "spam" now comes through Asian language IPs (cn & 
jp). I do have B, C & D(IP) blocks on Korean as well.

I actually get exceedingly litte spam from dynamic(sorbs?) IPs according 
to spamcop, so I've never bothered invoking a sendmail test(jargon?) on 
dynamic IPs.

My view is that "open proxy" (spamcop test*) gets a REJECT in access and 
no reporting address gets a "550 we dont want your spam" message" in access.

*Over a decade ago, when I started running a mail server(smtp) it would 
accept everything and then process it by various scripts. At the time, 
Sorbs decreed that my server was OPEN PROXY, which it wasn't. so I've 
been wary about this label ever since.

The good part was that I was sharing spam via CD for people who wanted 
to train their spam filters. Eventually I upgraded to sendmail and saved 
a enormous amount of incoming($$$) traffic.

Getting back to the point about ISPs. Apart from briefly having my 
current ISP provide DNS, I have never had any ISP require me to use 
their mail server or blocked releveant ports. Caveat, I will not use one 
that does.

Sadly, it is an issue of technical skills within the ISP. Dealng with 
DNS issues was bad enough, but I'm not lining up to learn the 
configuration of whatever mail server they think is flavour of the month 
and continually fixing their configuration.

Caveat, you probably can afford a better class is ISP if you are 
employed in a large company rather than running your own show.
