SPF Blocks SPAM, not sun's rays

A new technique known as Sender Policy Framework (SPF for short) may be the tool to get rid of those bounces that appear to come from you but really come from either a virus or a SPAM twerp that has your address. SPF works by having a domain publish (in their public DNS) a list of valid mail servers from which mail from that domain could be sent. SPF-conforming MTAs will shut down mail that couldn't have really come from the given domain. Find out more about SPF.
