Error #550 failed to meet SPF requirements from some domains. RRS feed

  • Question

  • Hello All,

     

    I have an issue with my Exchange 2010 & 2007 setup. I have two exchange servers (2007 & 2010) that send out to the internet with one public IP.

    I have mails flowing to other domains (even Microsoft) without issues. But to some domains, I get the error, #550 failed to meet SPF requirements. I have my SPF TXT record setup at www.instantregister.com as v=spf1 a mx:mail.domain.com -all.

    What am I not configuring right with the SPFs, Do I need to add TXT record in my Local DNS too?.

     

    Thanks.
