hotmail use spf, let recipient benefit from this, whitelist sender from address book with spf in mta level, no need to be smart :)
I'm not sure I understand what you mean by this could you elaborate? The email is coming from Hotmails server and therefore SPF is valid.
shourt: dont whitelist [EMAIL PROTECTED] whitelist [EMAIL PROTECTED]
I had considered that but manually adding/maintaining addresses would be a pain in the neck frankly - I briefly surveyed the logs for valid hotmail email and it turns out there is quite a lot being received by the mail server "unfortunately".
I have emailed [EMAIL PROTECTED] as recommended here by Stan and will see what happens but I think jumping on Spamassassins mailing list as suggested by Henrik and using bayes better will be my best bet by the sounds of it. Thanks
