issue creation by email fails when on-the-fly user creation fails
When issue creation is set up for creating unknown user on the fly, these users are created and identified by their email.
If email length exceeds 30 characters, the user creation isn't allowed and the issue isn't accepted. The user doesn't the reason.
Maybe would it be possible to create some valid identifier (salt+timestamp e.g) in this case for this user and still store his email in the email field, so his submitted issue would be registred ?
More generally, is it possible to prevent issue rejections because of user creation problems (or simply prevent automatic user creation rejections) ?
