I'm fine with Received-SPF being renamed when mail is received from untrusted host. But for mail received from our (trusted) mail backups: - the SPF check will apparently fail (thus I better turn if off) - I could trust the SPF headers made by them, but they get renamed to Old- I think the SPF check done by courier doesn't care if the mail is received from mail backup of recipient's domain. (This could be problem for multiple recipients). -- Matus UHLAR - fantomas, [email protected] ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
