Bug in validating E-Mailadress

[Taste-IT]

Hi,
after upgrading to latest Version and do an misstake in entering an E-Mailadress like domain.com, an invalid Mailadress, tine tries to send, but in my opinion has to check befor for an valid Mailadress.
Is this a Bug?

yep, seems to be a bug. I'll have a look.

btw. I'm getting this error:

index.php:153666 Uncaught (in promise) TypeError: Cannot read property '1' of null

This looks to me like it is related to #6870 because example.com looks to me like a valid mail address.

Please consider that the domain part of a mail address is optional, because of this example.com should be the same as example.com@localhost.
