The IP I send this from is static. It is also supposedly a "known" dynamic IP. I would agree with you if the dynamic IP lists were actually dynamic IP lists.
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.
