[Don't top post] This is wrong. You must not remove headers from other people's mail -- if my mail has those IPs in it, you must not alter it. At a minimum, add something like '.*by myhost.example.com' to restrict matches to headers added by your server. See the mail list archives for examples and details. If you still have trouble, show "postconf -n" output and the actual header you're trying to match. -- Noel Jones
