Hei tonioo,

using modoboa to manage a mailserver in germany i encountered a new issue. With modoboa it is not possible to add accounts having special chars within the local part of the email address (e.g. münchen@example.net) neither it's supported to add a domain using special chars (e.g. foo@münchen.de).
According to rfc 6531 this should be possible and nowadays many MTAs and MUAs support it.
The first case (local part) is prevented by the form validator (Enter a valid email address.).
The second case (domain part) isn't even validated leading to an internal server error (UnicodeEncodeError at /admin/domains/new/ 'ascii' codec can't encode character u'\xfc' in position 1: ordinal not in range(128)).

Bests

Hei tonioo, using modoboa to manage a mailserver in germany i encountered a new issue. With modoboa it is not possible to add accounts having special chars within the `local part` of the email address (e.g. `münchen@example.net`) neither it's supported to add a domain using special chars (e.g. `foo@münchen.de`). According to [rfc 6531](https://tools.ietf.org/html/rfc6531) this should be possible and nowadays many MTAs and MUAs support it.
