title: Controlling where "out of office" replies are sent
body: <p>How do mail servers decide when and where to send &quot;out of office&quot;-type autoreplies?</p>
  <p>It seems this is mail server dependent, so some will use a reply-to: address, others the From: and perhaps the Sender: address. Some servers (or all?) seem to care about the Precedence: field and will not send out of office replies at all on Precedence:bulk (or maybe precedence:list?). The return-path seems to be used for more severe types of bounces, but maybe it's used as well?</p>
  <p>What I want is to achieve (this time) is to minimize the number of response e-mails that go to the from: address. I don't mind getting them at the reply-to address.</p>
  <p>I've been looking for some sort of reference or best practices - any references or suggestions? I 've looked at some relevant RFCs (<a href="https://www.rfc-editor.org/rfc/rfc2822" rel="nofollow noreferrer">RFC2822</a>, <a href="https://www.rfc-editor.org/rfc/rfc3834" rel="nofollow noreferrer">RFC3834</a>) but I'm looking for how things are actually handled.</p>
