Given the reputation of the Azure IP space, be hesitant to start operating an email server there, UNLESS you can get MS to give you SWIP or 'rwhois' for your IP space.
Just an FYI..
High levels' of AUTH attacks originating from that space as well. To the point we even have a reputation list just for that IP space, in case you want to block AUTH attacks from it.
There was a quote from an MS engineer who even placed doubt on accepting an email from the Azure space.. of course, the world evolves, but without a 'rwhois' or SWIP that shows transparency, I would not recommend it..

I have a question regarding the Dovecot Server compatibility with Azure Cloud, which our application is migrating to. We are currently using Dovecot Mail Server v2.3.4. I need to verify that the software is compatible with that type of environment or what we would need to continue using the software once we migrate. Thank you,
