 Auto-search for new PMs - other language

I have a problem with auto-search for new PM. I'm playing on polish server, with changed PM format. There's no "[OtherPlayer -> me] and [me -> OtherPlayer]", but "[OtherPlayer -> Ja] and [Ja -> OtherPlayer]". I've been looking for regex, but failed. I can't make it work :( Anybody could help me please?
