Hm, debatable, as you then have to check for possible encoding too.

Good point.

That is in invalid from header value. If I'm not mistaken, then, per
RFC5322, an unquoted display name must not contain "@".

exim -be '${sg{${sg{"h...@foobar.com" <hans @
example.com>}{:}{\\\\:}}}{\N^\s*\S+@\S+\s*(<\S+@\S+>)\N}{\$1}}'
"h...@foobar.com" <hans @ example.com>
So it doesn't extract the address, but it returns something ${domain:<string>}
can extract a domain from.
If that is your intention, then I fail proving it being wrong :)
> Try to check ${addresses:mailb...@domain.tld <mailb...@domain.tld>}
Same as above - the input to ${addresses:<…>} is invalid per RFC5321.
