I searched the web for hours in order to find an answer on how to change the administrative email of the dns zone when using plesk.

First of all I want only one email address in all zones to be entered and not the customers email address.
And also when there is an email in the format of some.name@domain.com plesk inserts a slash !
So you get a some\.name.domain.com !

So many years of development of the plesk control panel and they couldn't create an email field for the SOA record ???!!!!
How crazy can that be ?
