SPF always temp errors, WTF

jrdaijrdai Member

Received-SPF: temperror (encountered temporary error during SPF processing of domain of mail.test.com)

My setting in the DNS is :
mail TXT v=spf1 ip4:198.xx.xx.xxx -all 600

I must have missed something important. Is it the hostname must be exactly the domain sending emails? Or is it rDNS setting?

    Have you set rDNS?

    Check your mail headers for the hostname/IP that the mails are coming from if you have more than 1 IP.

    what's 600 there?

    v=spf1 a ip4:18.xxx.xxx.11/32  ?all

    This is how I usually do it...

    IP.ADD.RES.S01 - is the shared/dedicated IP for the site

    IP.ADD.RES.S02 - is the servers host IP that exim is usually running on

    server.hostname.tld - is the servers hostname that the rDNS points to for IP.ADD.RES.S02

    mydomain.tld - its TXT entry is "v=spf1 ip4:IP.ADD.RES.S01 ip4:IP.ADD.RES.S02 include:server.hostname.tld ~all"

    server.hostname.tld - its TXT entry is "v=spf1 a mx ~all"

    Make sure that rDNS for all the IPs matches and isn't generic.

    No, is it because of that?

    It is the TTL.

    Thank you @DeanClinton for detailed explanation.

    So, I need to set the hostname the same as the one sending emails? So if my hostname is plato.test.com, and emails sent are mail.test.com, and the SPF/DKIM are setting for mail.test.com, in such case SPF checks will fail?

    you've got a better chance of passing if everything matches and is referenced correctly in the SPF and also the rDNS.

    So if the hostname is host1.mydomain.com then include the host1.mydomain.com in your spf and also make sure rDNS is set correct.

    Disclaimer: I'm not a guru.. just explaining what I did and it worked.
