DNS PTR Record with VM and Slave DNS

Virtualmin

Test dmarc

I didn’t know about this last test and unlike others it reports several problems both on SPF, DKIM and DMARC.
However, with the Cluster Slave I no longer manage the TXT Records, but Virtualmin manages them.

You need to sort out that else mail will go to spam, especially with gmail.
Gmail headers should show the issue, if you use “Show Orginal” from the 3 dot dropdown on the right top.
This is what you should be aiming for.

That’s exactly the point, I’m not the one who has to fix this because SPF, DKIM and DMARC are automatically generated by Virtualmin in Virtualmin /virtual-server / DNS Settings / DNS Options.

@Joe
If VM generates records in the wrong format, then there is no need to manage VM + Cluster DNS (WM).
At least this way TXT records can be created by hand.
Google has become very strict with “anti-spam” parameters

I found the point where to do the configuration for SPF, DKIM and DMARC.
System Settings / Server Templates / DNS Domain
It wasn’t easy, I had to go through the menu item by item, tab by tab, field by field.
The documentation doesn’t help; fortunately there is also online help for the individual fields.

Meanwhile, I was finally assigned the PTR.
So I’m closing the thread.
Thanks again everyone.
