EnglishHi Guys
When trying to add an External Sender on a mailbox I get the error that "External sender “name” uses an invalid domain.
When adding the domain “example.com.na” (my country TLD is .na) it does not allow me to add the domain but when I use “example.com” it accepts it.
Any ideas?
I just tested it with “test@example.com.na”, no complaints from the UI
Have something to say?

ID10T Error.
I used the real domain, and example.com / example.com.na was just for forum anonymity purposes. The actual domain was still on the system as a Mailcow domain, when I was doing tests with setting up as relay domain and aliases.
Once the true .com.na domain was removed it allowed me to add the domain as an external sender.
