* About umlaut or IDN domains: we currently only allow German umlauts in domain part!
* We forbid all non-ascii chars in local part, as Horde does not yet support SMTPUTF8 extension (rfc6531)
* Client-side forbids all non-ascii chars in local part, as Horde does not yet support SMTPUTF8 extension (rfc6531)
* and we get a "SMTP server does not support internationalized header data" error otherwise.
* We can't do that easily on server-side, as used \x80-\xf0 works in JavaScript to detect non-ascii,
* but gives an invalid utf-8 compilation error in PHP together with /u modifier.
*
* Same preg is in et2_widget_url Javascript class, but no \x00 allowed and /u modifier for utf8!
