myhostname and Postfix
Vmin GPL
CentOS Linux 7.4.1708
Hi,
In an attempt to understand why my emails are ending up in Outlook.com spam folder I've been looking at the email headers and have noticed that the
'Received: from' and 'HELO' fields are server1.mydomain
which according to an email tester is not associated with my ip address, my rDNS is server1.mydomain.com
Postfix main.cf file has
myhostname = server1.mydomain
which would be the reason for the 'Received: from' and 'HELO' fields in the email headers.
