I have asked for some help last week about email addresses and CharlieS gave me a Regex formula that covers 85% of the syntax errors I could meet.
here is the great Regex formula
However it rejects some email addresses which are correct
(i) Some emails have two dots in their domain name or a dash, which are both accepted.
(ii) Some emails have been set as FALSE for some reasons I do not understand
info@Kavitation24.de (digits in the domain name?)
Woelk&Partner@online.de (ampersand is allowed in email syntax)
do you know how I can get them set as correct addresses?
