Hello, I'm running Postfix 3.6, I just upgraded. I do not know if this issue occurred because of the upgrade or prior to it as I hadn't sent any mail through this account lately.
I'm having an issue with spf, error log below, if I comment out check policy for spf under recipient_restrictions things work fine, turn it back on and this is the log that I get, addresses obfuscated.
