Hi,
I have just run a test against one of my servers.
1. dmarc, well I do not have one either. Not sure if I need to either.
Does anyone else have one?
2. check what the "host" command for your ip returns against the "me" file
in /var/qmail/control/me
Might pay to edit the "me" file and put in
Friends,
If I check my server with
http://mxtoolbox.com
I get the following complaints
Category Host Result
dmarc theppsgroup.com Missing or Invalid Record
smtp mailhost.theppsgroup.com Reverse DNS does not match SMTP
