Hello, I get warnings about the PTR record not being set from Google and so cannot send email to any gmail user it looks like.
My DNS records:
@ A **1.2.3.4** (links to webdomain.org)
mail A **5.6.7.8** (links to mail.domain.com)
mail AAAA x:x:x:x:x:x:x:x (links to mail.domain.com)
autoconfig CNAME mail.domain.com
autodiscover CNAME mail.domain.com
@ MX 10 mail.domain.com
@ TXT "v=spf1 mx a -all"
_dmarc TXT "v=DMARC1; p=reject;"
dkim._domainkey TXT "v=DKIM1;k=rsa;t=s;s=email;p=keyhere"
The domain set in my Mailcow conf:
MAILCOW_HOSTNAME=mail.domain.com
My VPS service provider confirmed that that the correct PTR records are set:
Name: mail.domain.com
Address: 5.6.7.8
Name: mail.domain.com
Address: x:x:x:x:x:x:x:x
I have updated and restarted Mailcow and it’s the same result.
Does anyone know what else I could investigate?
Thank you!
