My mails keep ending up in the junk folders of gmail and microsoft. The mail server uses postfix and dovecot and has the following setup when it comes to ssl
server.domain1.ext - Hostname used by postfix and dovecot
The server handles mail for the following domains, server.domain1.ext support.domain1.ext domain2.ext domain3.ext
Should I also include the other domains than server.domain1.ext in the certificate used by the mail server or is just the hostname enough.
The mail server has dkim and spf properly set up and scores 10/10 at mail-tester.com
What step can I take to make sure my mails end up in the mailboxes of the recipients?
