Yeah, we're on it. Seriously considering not being so strict about the domain name. There was stuff from Brad Fitzpatrick when LiveJournal allowed them a few years ago - saying pretty much everything allows underscores in web stuff. Wondering if it's worth fighting the "standards complient" fight. http://bugzilla.cyrusimap.org/show_bug.cgi?id=3341 Bron ( and FastMail is now blocking _ in our postfix rules: +/@.*_/ REJECT Domains cannot contain underscore )
