Sorry, meant to attach the relevant bits...
email address = localpart @ domain.
localpart can be any number of atext chars, plus a '.' anywhere byt the
first character.
domain follows the same basic rules as the localpart, except that you can
add text before it, '<>' around it, etc.
atext = ALPHA / DIGIT / ; Any character except controls,
"!" / "#" / ; SP, and specials.
"$" / "%" / ; Used for atoms
"&" / "'" /
"*" / "+" /
"-" / "/" /
"=" / "?" /
"^" / "_" /
"`" / "{" /
"|" / "}" /
"~"
Of course, you can also use quotes if you want to add other characters
outside this set, but lets not get into that!
