Email notifications
Description
I know that e-mailadresses with "ß" are invalid in general, but you can enter them in redmine. That causes that any notification to a ticket which are related to the person with the "ß" mail couldnt be send.
The "to:" mailadress in the maillog is something like "to=<=?UTF-8?B?bWFyY2VsLnBsYcOfQGJ1cmctZ21iaC5kZQ==?=>" for everyone who is related.
-> No one will be notified.
- Subject changed from E-Mail with ß causes error to Email address with non-ASCII character causes delivery error
Non-ASCII characters cannot be used in an email address.
This issue can be fixed by the following patch.

Yes, they can. More and more clients and server support that.
We cannot simply disallow them in Redmine.
