Server 1 (CPanel):
Email: [email protected]
Server 2 (HestiaCP 1.7.2):
I have added server 2’s SPF and DKIM records to server 1’s DNS zone, however if I want to use Server 2’s mail server (mail.sub.domain.tld) to send emails using the [email protected] email address the header does not have a DKIM signature.
I’m not sure if this is configured intentionally on Hestia CP, but before when Server 2 used CPanel it worked and I could send DKIM signed emails using the [email protected] email address from the mail.sub.domain.tld mail server.
Can I make any changes to exim to DKIM sign emails sent from [email protected] using the mail.sub.domain.tld mail server?
