Can't receive, but send Emails

[CloudLessTV]

Hi KeyHelp Community,


I recently installed the KeyHelp Panel and set it up.
I tested several Lookups at https://mxtoolbox.com
The DMARC Lookup shows this warning: "External Domains in your DMARC are not giving permission for your reports to be sent to them."
And the Supertool prints out this warning: "Reverse DNS is not a valid Hostname".
The Email-Health tool prints out this warnings:
- "Reverse DNS does not match SMTP Banner"
- "Warning - Does not support TLS."
- "May be an open relay."
- "SOA Serial Number Format is Invalid"
- "SOA Expire Value out of recommended range"

My Setup is like this:
I've got one Domain, that I use for the KeyHelp Panel, set up with Wildcard and Root, both as A-Record.
My second Domain has a PTR Record pointing to the first Domain, one TXT-Domainkey, one DMARC- and one MX-Record aside from Wildcard- and Root-A-Records.

At this point I don't really know what to do, I'm pretty new to this stuff.
If you need any more information, just ask.

Thanks in advance!


Kind regards

At first, fix rDNS.

Then, why is the SOA invalid, do you use an external DNS?

A common way to create the serial is using: YYYYMMDDxy, where xy counts up from 00 for each changing on that given day.

Sry, that I come back to this, this late.
I'll try it without Cloudflare and will come back to this thread after that.
