PHP version 7.2.31
BIND - NOT IN USE
I’ve enabled DKIM and added the relevant TXT record at the Registrar and for the 1st mail enabled Virtual Server - outbound emails sign as expected.
I’ve created a 2nd Virtual Server - just HTTP & HTTPS, with no mail. It’s mail is hosted elsewhere.
A webpage has a contact form - it works, as in the email arrives in the yahoo inbox (for testing purposes). Looking at the headers - the message is DKIM signed.
I’ve gone into Virtualmin >> Email Settings >> DomainKeys Identified Mail and added the domain associated with this new Virtual Server in the “Never Sign for domains” field, clicked save and even reloaded\restarted Postfix for good measure.
Sending another email via the webform and examining the headers, it is still DKIM signed.
Any help\advice\pointers would be greatly appreciated.
