port 25 open. There are multiple ways to detect dynamic IPs (rDNS
patterns,
PBL, SORBS-DUL, MAPS-DYNA) which I found more safe than TCP port 25
open.

if an IP is dynamic, it does not matter whether it has port 25 open.
I gave good examples why it should not be whitelisted. Not all ISPs block
incoming port 25...
i did not say its not more test to do
well I don't see a reason to test for port 25 open, maybe to block open
relays and/or SMTP redirect on misconfigured routers...
This is what e.g. rfci-ignorant or many other rhsbl blacklists are
for.
thay are dead
they are alive on rfc-ignorant.de :-)
