Outgoing SPF

Neomailbox now publishes SPF records for its SMTP servers. SPF (Sender Policy Framework) is a proposed Internet standard to provide a method for SMTP servers to prove to each other that they are authorized to send mail for the domains they appear to be sending mail from.

The idea, of-course, is to make it harder for spammers to send mail with forged headers without being detected. We're working on also adding SPF headers to incoming mail, so you can set up filters based on this information.
