Can't speak about the other issues you are having, but is this regexp pattern what you want? Unless Postfix PCRE automatically right-anchors these regexps, aren't you rejecting mail from someone@mail.twinpeaks.org, or even twitter notifications (from *@bounce.twitter.com)
I am not sure I even understand what you were trying to say. It's either because you have no idea how to write any regexp
the only one having no clue are you (bseides wrong mailing-list)
/^From:.*\@.*\.tw/ is bullshit and matches twitter.com and so on /^From:.*\@.*\.tw$/ at least would make sure it *ends with* tw
frankly your rule matchs *anything* having a @ and .tw
