(I answer to the list also for clarification) Example: you allow mailserver "My_MX" in your SPF. you send mail to [EMAIL PROTECTED] (with MX server mail.brown.test) he has a forward to mailsrv1.zmi.at (our server). Our server then sees a message from [EMAIL PROTECTED] coming from server mail.brown.test, and checks SPF for your domain, and this server is not on the list. Would you like to extend your SPF to mail.brown.test just because charly wants his e-mail on another server? You're not trusting mail.brown.test, so you should not allow that in your SPF. You would have to put every mail server on your SPF from people who forward *their* e-mail to another server which checks SPF. That's a bit tricky and requires a bit time to understand, I've got headaches in the first debug of a rejected SPF e-mail too... mfg zmi -- // Michael Monnerie, Ing.BSc ----- http://it-management.at // Tel: 0676/846 914 666 .network.your.ideas. // PGP Key: "curl -s http://zmi.at/zmi.asc | gpg --import" // Fingerprint: AC19 F9D5 36ED CD8A EF38 500E CE14 91F7 1C12 09B4 // Keyserver: www.keyserver.net Key-ID: 1C1209B4
