Thanks, but do you know that is not perfect too? Eg. try
add "(comment)" after address and will match invalid
address... Some time ago i search email address regex
on Internet, and what i found as full RFC compliant
was horrible complicated, with questionable performance,
not manageable (i lost in it) and for ASCII only...

That is IMO OK, as this will not pass header_syntax check,
thus one can consider that as expected to don't parse...
