Related to the actual cause of the problem, I apparently was testing some SMTP stuff a while back and disabled my rule to block all SMTP outbound on my network, then forgot to turn it back on. That rule is enabled again, so now waiting to see when it gets hit to find out what the hell on my system is sending spam.

But, this still does not resolve the MS problem with the white listing until the CBL drops off.

What the Adavantage with Pbx in a flash? That's the only one I haven't used. I've mostly used FreePBX (and some straight up asterisk)

The PBX in a Flash team also has a lot of nice extra features baked in and some that you can add (Traveling Man is a good example).

PBX in a Flash existed long before FreePBX had a distribution of its own. Obviously, PIAF uses the FreePBX GUI just like Elastix.unli,e Elastix, they do not wrap everything around in their own GUI. All that PIAF does is add a quick and dirty landing page to let you access the various tools directly from one place.

You basically need to know more to truly admin a PIAF system well.

It is also heavily focused on security.
