    <p>Hi,</p>
    <p>Just looking into this in more detail:<br>
      <br>
    </p>
    <pre>Return-path: <a class="moz-txt-link-rfc2396E" href="mailto:bounce+123194+7+8112995+12921448@groups.io"><bounce+123194+7+8112995+12921448@groups.io></a>

So yea, that's VERP based.

From: "Joshua Colp via groups.io" <a class="moz-txt-link-rfc2396E" href="mailto:jcolp=sangoma.com@groups.io"><jcolp=sangoma.com@groups.io></a>

And that's a very basic form of SRS ...

And these headers are present too:

List-Subscribe: <a class="moz-txt-link-rfc2396E" href="mailto:asterisk-dev+subscribe@groups.io"><mailto:asterisk-dev+subscribe@groups.io></a>
List-Help: <a class="moz-txt-link-rfc2396E" href="mailto:asterisk-dev+help@groups.io"><mailto:asterisk-dev+help@groups.io></a>
Sender: <a class="moz-txt-link-abbreviated" href="mailto:asterisk-dev@groups.io">asterisk-dev@groups.io</a>
List-Id: <asterisk-dev.groups.io>


So yea ... for filtering properly you need to handle groups.io specially.  It's a pain but perfectly do-able.

Kind regards,
Jaco
