Oh... I really missed the "comment". Maybe because in real life I met it

I think that in this case it is not necessary to use a very "horrible
complicated" full RFC compliant regexp. It may be sufficient to ignore
all parenthesized text after the last ">". Or even ignore all text in
parentheses after the last ">".
${if
eq{${addresses:$rh_From:}}{}{${sg{$rh_From:}{\N^.*<(\S+?@\S+?)>[^>]*$\N}{\$1}}}{${addresses:$rh_From:}}}
