Original GitHub issue: https://github.com/acme-dns/acme-dns/issues/208

Just curious about the automatic substitution. Why is this being done?

# admin email address, where @ is substituted with .
nsadmin = "contact.example.com"

This will be transformed to contact@example.com.
What about the valid addresses that have a . before the @ symbol?

Wouldn't firstname.lastname.example.com be translated to firstname@lastname.example.com, when it should be firstname.lastname@example.com?

Cheers! This is because of the format of the SOA record.

That said, you just identified a lack of documentation for that comment. The actual dots in the e-mail address (except for the TLD) should be escaped with \, so firstname.lastname@example.com should become firstname\.lastname.example.com.

I think the comment should be fixed. Do you want to create a PR, or should I?
