They're nuts, I know. They're blocking mail from my spaniard friend too,
he has a static IP on DSL...

No, no, I think you're slightly mistaken. They're refusing to deliver
mail from 'residential ips'. That is, say my Spaniard friend
sends mail to me using his localhost SMTP server. Once the message
gets to the RR mail server, the RR mail server bounces it.
I don't run a SMTP service for other people, I run it for *myself*,
as it is the easiest way of getting Mutt and a few other MUAs to send
mail.

Er? This may be common, but it isn't normal. This is contrary to several
RFCs on email, I think...

I don't understand that paragraph very well. ;)

Oh yes, it stops spam wonderfully. Only 90 messages in my Spam/
folder this morning! And several people I actually want mail from,
have to modify their mailserver setup in order to mail me.
Wonderful system. ;)
At least, I don't feel bad about having Fetchmail poll their POP3
servers for mail every minute or so any more.
However, if RR were to just ignore all mail from Asia and former Soviet
bloc countries, I'd have a *lot* less spam...
