Exim puts for address in the Received: headers of some, but not all, messages. Is this a bug?


No. It is deliberate. Exim inserts a for phrase only if the incoming message has precisely one recipient. If there is more than one recipient, nothing is inserted. The reason for this is that not all recipients appear in the To: or Cc: headers, and it is considered a breach of privacy to expose such recipients to the others. A common case is when a message has come from a mailing list.
