Mandrill: SPF Permanent Error: Invalid domain found (use FQDN) -
i'm trying set mandrill 1 of our client's domains receiving error when trying set spf record:
an unexpected error occurred while checking domain: spf permanent error: invalid domain found (use fqdn): 123.123.123
the domain has current spf record follows:
v=spf1 mx ptr ptr:123.123.123 ~all
as per mandrill's instructions should add existing record follows:
v=spf1 mx ptr ptr:223.197.169.174 include:spf.mandrillapp.com ~all
which results in above error. have tried creating new record instead, mandrill didn't like. ideas can do?
the ptr mechanism should specify domain-name , not ip-address. if no domain specified default domain used.
but discouraged using ptr mechanism, since can put heavy load on resolving server (http://tools.ietf.org/html/rfc7208#section-5.5)
so think record looking it:
v=spf1 mx include:spf.mandrillapp.com ~all
or
v=spf1 mx ptr include:spf.mandrillapp.com ~all
if still want ptr
mechanism.
