I'm currently using 2 providers to send e-Mails and one host which directly sends e-Mails.
Personal mails are sent via Google and application generated via a bulk e-mail provider.
Both are sent from the same domain (
Google specifies to use this record ("Create SPF records"):
v=spf1 include:_spf.google.com ~all
The other provider specifies:
v=spf1 include:spf.provider.com ?all
I created the following TXT record (ip4 value changed):
v=spf1 ip4:127.0.0.1 include:_spf.google.com include:spf.provider.com ?all
I have tested this by sending mails via both providers to a Googlemail address and it passes.
However the email@example.com service of port25.com reports (again hostnames/IPs changed):
Result: permerror (multiple SPF records) ID(s) verified: firstname.lastname@example.org DNS record(s): example.com. SPF (no records) example.com. 3600 IN TXT "v=spf1 ip4:127.0.0.1 include:_spf.google.com include:spf.provider.com ?all" example.com. 3600 IN TXT "google-site-verification=$hash$" _spf.google.com. SPF (no records) _spf.google.com. 300 IN TXT "v=spf1 ip4:22.214.171.124/19 ip4:126.96.36.199/19 ip4:188.8.131.52/20 ip4:184.108.40.206/18 ip4:220.127.116.11/17 ip4:18.104.22.168/20 ip4:22.214.171.124/16 ip4:126.96.36.199/20 ip4:188.8.131.52/20 ip4:184.108.40.206/16 ?all" spf.provider.com.

Is this verifier correct with its conclusion?
