Description of my issue
Hey hello everyone
I know this is nothing but a new problem, and there is plenty of issues already posted about this, but here I am and hotmail is blocking again emails from our domain, and lots of sweet people cannot write anymore to their dear friends they care about. I’ve already told them that they’re best solution is to tell to their sweet friends that freedom will feel good to them when leaving hotmail, but this takes some time and in the meantime, I’m writing to microsoft again and again asking them to remove our domain from their intentional small providers blacklist.
But doing all this, I checked a bit the ratings of our domain on some tools and got some results I don’t fully understand, so I was thinking maybe here some people would have nice insights on those results:
1 - mxtoolbox.com
It says that everything is fine, but displays a warning saying: DMARC Quarantine/Reject policy not enabled
. I’m using the standard recommendations of yunohost for DMARC record so I don’t fully understand what that mean. Any idea?
2 - mail-tester.com
It gives a rating of 10/10, but specifies somewhere that:
Your reverse DNS does not match with your sending domain.
IP: XX.XXX.XXX.XXX
HELO: domain.tld
rDNS: sub.domain.tld
I don’t think this should be a problem, since in domain.tld
's DNS record there is
@ 3600 IN MX 5 sub.domain.tld.
and
sub 3600 IN CNAME domain.tld.
So the redirection should be fine, from what I understand.
Anyone sees a problem in that or has an idea why mail-tester is complaining?
Thank you for any advises and take care
