Sender Policy Framework SPF – SPF How To & Help

I don’t know about you but all this Sender Policy Framework SPF stuff is pretty confusing to me…

Here’s some resources to help you guys…

These guys can help sometimes (free and they volunteer) but don’t expect a fast response and please try to get help on the forums first:

IRC – Internet Relay chat – If you need real-time help, e.g. for debugging, you can join the #spf IRC channel on irc.perl.org.

Here’s a step by step wizard to setup your spf record – http://old.openspf.org/wizard.html

Another SPF record testing tool – three actually on the page
http://www.kitterman.com/spf/validate.html
One will check if your domain has a SPF record and if it’s valid, one will check the syntax of your SPF record and the third will check deliverablilty against certain hosts.

subdomain SPF records – http://www.openspf.org/FAQ/The_demon_question
Make sure to publish SPF records for subdomains as well. If you use wildcard domains for sites like wordpress MU something like this would work –

Sites with wildcard A or MX records should also have a wildcard SPF record, of the form: * IN TXT “v=spf1 -all”
