Note Submitter: desert at deserteagle dot at ---- I have to correct eric at devotia dot com a bit, because domainnames are restricted in some weird, tld depending way. Some TLDs allow special chars like umlauts, others allow only ascii - so there is no way of ensuring syntactically correctness of a hostname, because there are only a few chars, wich are never allowed - i guess, a \w will do. Furthermore, the @ is allowed as userpart of the emailaddress, in fact, at least one (1) char has to be given, no matter which one.
