Hello people, I was trying to modify the SPF by API, and realized that it is duplicated. In DNS records. See attached image.
I tried on two machines, they have the same problem.
By modifying the UI-Virtualmin in "DNS options" set to disallow, the same problem happens.
The SPF record is duplicated. Note: If you try to delete one, the two leave.
It seems that this is not normal.
bye, sorry English.
