Thanks for sharing this information as I had not heard about this yet.

<p>Back in the day we used aggregation points for inbound and
outbound mail. That involved a dedicated inbound box to filter
spam and an outbound "smarthost" for sending. Those days are long
behind us now. There were reasons for setting things up but as
times have changed (we're no longer limited by resources of a RaQ2
or RaQ3) we've adjusted our design over the years. <br>
</p>
<p>Given that BlueOnyx (and the other systems) we use support DKIM
out of the box these days, there's little reason to force email
out a separate box. It just creates a layer of complexity that
doesn't need to exist. <br>
</p>
<p>That said, if you want to use DKIM then you'll need to configure
that on your relay server. I don't know what you're using for
this purpose, but we have a Knowledgebase article that might give
a nudge in the right direction. It was created with older
BlueOnyx installations in mind before DKIM integration made it to
the GUI. While I can't promise this will work in every case (or
even your specific case!), perhaps it will be helpful:</p>

<p>But give some thought on the relay matter. Is that still the
best way forward given the current landscape? That's a question
I would ask myself but wouldn't answer on your behalf. ;)<br>
