The answer is No, this does not and will not work.
the full answer is…
I have been working with Comodo for many months on this. The problem is that using Office 365 works, but Microsoft class the IP of the sending server as spam; and as such is sent out using the HRDP (High Risk Delivery Pool).
The HRDP list of sending IPs are classed as spam by everyone meaning no one will get your tickets.
We have a spam filter which I have opened up a communication channel on to allow us to send as our domain.
The answer is YES, i have added Comodo’s IP’s to microsoft, i had it working but it stopped, i had a call with a support member, we setup my settings on her platform and it worked with no problems, the problem is with my SD, they are looking in to why it does not work.
FYI, create a receive connector in O365: Onsite Connector
