Can you explain a bit more what you mean? A message should always end up with exactly one Return-Path header, which is put in by the final (delivering) MTA. This is not something sieve has any control over: the rejection message sieve submits for delivery should not have a Return-Path header at all, since that information is (at that point) carried in the SMTP envelope. (In the case of a reject message, since this is an MDN, the SMTP FROM should be the null address <>.) Ben
