Hi there, we're Email Service Provider company. As you know, the cPanel automatically signs outgoing emails with DKIM and SPF records. We've done that. But the problem is that our emails are not signed with DomainKeys (we know it's older version of DKIM but Yahoo Mail still checks both DomainKeys and DKIM) and so it's not getting pass the Yahoo Mail's spam check. How do i configure and make the emails signed with DomainKeys? Here is the result of email header sent to Yahoo Mail: Received-SPF: pass (domain of xxxxxxxxxxxx designates xxxxxxxx as permitted sender) Authentication-Results: mta1678.mail.gq1.yahoo.com from=xxxxxxxxxxxx; domainkeys=neutral (no sig); from=xxxxxxxxxxxx; dkim=pass (ok) Also here is the result of Port25's email authentication: ========================================================== Summary of Results ========================================================== SPF check: pass DomainKeys check: neutral DKIM check: pass Sender-ID check: pass SpamAssassin check: ham thank you!
