Yes, even if said frequency is very low. If my ISP does not give me a
guarantee that when I reconnect I will get the same address again, and
that noone else is going to use that address, I consider it a dynamic IP.

Hrm, that would indeed be a reason to accept mail from some IPs inside
such "dynamic" blocks. Your IP does not seem to be listed as being
dynamic, though. :-)
OTOH, I think greylisting can help here, by applying it to hosts that
are listed as being dynamic. If the technology your ISP uses to connect
you to the internet is so strikingly similar to the technology used by
people who don't even care whether they have a fixed IP, I would assume
your bandwidth would not allow you to send amounts of mail that
greylisting would adversely affect you. :-)
