On top of that, I suggest to clearly describe the requirement to quote any "leading" dot(s) that are *not* supposed to be converted to an '@' character. Like in wilfried\.woeber.univie.ac.at !
Wilfried Woeber : e-mail: Woeber@CC.UniVie.ac.at
While this particular hack works, it is a clear violation of the spec.

Which specs? At least this recommendation is part of RFC 1912:
2.2 SOA records
In the SOA record of every zone, remember to fill in the e-mail address that will get to the person who maintains the DNS at your site (commonly referred to as "hostmaster"). The `@' in the e-mail must be replaced by a `.' first. Do not try to put an `@' sign in this address. If the local part of the address already contains a `.' (e.g., John.Smith@widget.xx), then you need to quote the `.' by preceding it with `\' character. (e.g., to become John\.Smith.widget.xx) Alternately (and preferred), you can just use the generic name `hostmaster', and use a mail alias to redirect it to the appropriate persons. There exists software which uses this field to automatically generate the e-mail address for the zone contact. This software will break if this field is improperly formatted. It is imperative that this address get to one or more real persons, because it is often used for everything from reporting bad DNS data to reporting security incidents.

Ok, I was overly zelous in my reading of RFC1035. I like what Dave has published in RFC1912. --bill
