Topic: adding SPF and DKIM record for ISP relayhost
i recently using relayhost with my ISP smtp as a relay
because my mail server IP always blocked on yahoo, gmail and hotmail
so i use my ISP smtp server to send mail from the iredmail
when i send mail to yahoo, i get header like this:
Received-SPF: fail (mta1079.mail.ac4.yahoo.com: domain of firstname.lastname@example.org does not designate 125.160.6.xxx as permitted sender)
125.160.6.xxx is my ISP IP address, not my mail server
and also this:
Authentication-Results: mta1079.mail.ac4.yahoo.com from=unhas.ac.id; domainkeys=neutral (no sig); from=mydomain.net; dkim=permerror (bad sig)
how to fix that ?
