Weeeell, the dynamic IP I have at home is dynamic, in fact they cut the
connection every 24 hours to ensure I get a new IP. No problem because I
push all my mails to a machine with a static IP so I don't have to send
directly ;-). Anyway, the scheme dwmw2 mentioned (white list IP plus
HELO host) should alleviate most false whitelisting due to dynamic IPs.
