I'm runing config3 on lenny as per perfect guide and the name server set up as per the schlundtech guide Mail mostly works fine. I can send mail to googlemail and yahoo without it landing in junk folders. Recently however I've had a trouble sending to a couple of domains. I received this mail back: the other rejection I got a couple of days ago was from a netgear email.. as below: The only thing that springs to mind, and this really is a guess, when i set up the name server records as per the guide, I couldn't work out how to create the SPF records in config3. Any ideas much appreciated?
