Local Address Extension with + not validated by E-Mail-Validator @ DNS-Wizard
I found another - i think - bug in validators. The E-Mail-Adress-Validator does not allow a + to be used.
Thus technik+dns@example.com is not allowed as DNS zone's contact E-Mail but technik@example.com would be allowed. This does not apply to e.g. new customer.
Is there any reason for this not being valid I did not find?
