The point I was trying to make is that MailScanner works like this (oversimplifying, I know, but bear with me):<br><br>1. First instance of sendmail grabs e-mail after milters and such, and deposits in an incoming queue<br>
2. MailScanner grabs, scans, deals with messages in the queue and places them in the outgoing (final) queue<br>3. Second instance of sendmail grabs e-mail from outgoing (final) queue and delivers them to their final destination.<br>
<br>In order to DKIM-sign things it would have to be done using the second instance. Since MailScanner basically runs the same instance of sendmail using a command line parameter to distinguish the two, there would have to be a slight change to the way step 3 is done if you wanted to do it on one machine. Otherwise step 4 would be to have the outgoing MTA (separate machine) do the DKIM signing.<br>
<br>Please correct me if I'm looking at this the wrong way.<br><br><div class="gmail_quote">On Mon, Jun 22, 2009 at 1:42 PM, Rick Cooper <span dir="ltr"><<a href="mailto:rcooper@dwford.com">rcooper@dwford.com</a>></span> wrote:<br>

<div></div>Any chance of someone thinking up a way to fire up a third instance
of sendmail on one machine to do something like this?<br><br>

don't want to sign dkim or domainkeys until the last thing before
the<br>message is "place on the wire". Any modification made after the
signing<br>with, of course make the signature invalid. This means the outbound
MTA has<br>to be the signing agent.<br><br>Rick<br><br>-----Original
