[Bug]: Email Address Without Top Domain is Validated

[Dan-Karlsson]

Describe the issue

The email address test@contoso is validated as a correct address. This makes it possible to enter bad email addresses which isn't noticed until trying to send.

Expected behavior

The email address should be stopped at validation, not when sending the email.

Steps to reproduce

1. In Email Accounts press Send Test Email.
2. Select Other...
3. Enter test@contoso
4. The error ends up in the Outbox instead of a validation error

Alternate way to reproduce in Cronus

1. Go to customer 10000
2. Remove .com after contoso in field Email
3. Don't get a validation error

Additional context

It is possible to fix in codeunit 8889 "Email Account Impl." in function ValidateEmailAddress().

But maybe it should be fixed in DotNet MailAddress.MailAddress() instead?

I will provide a fix for a bug

Technically those are valid email addresses.
Although such email addresses are not recommended.

True, and blocked in Microsoft Exchange. Not allowing addresses that can't be sent to through Microsoft's products would be a reasonable restriction in my eyes.
