And then you get something as this:
From: "postmaster@???" <charles@???> (<confuse@???>)
:-)))
My point was, that regex can be not reliable too.
I consider the ${address:} expansion as way to prevent needing that
anyone have to develop own parser, which can end in ugly or even wrong
way as not all (including me) are regex experts...
I do not expect, that ${address:} will parse any wrong syntax. I can
accept, that it can fail in some corner cases of valid syntax. But
i expect, that when header will pass the header_syntax check, then that
expansion will be able to parse it, otherwise something is wrong.
