The reason I am wanting to do this is I would like to know if people are getting their email on personal devices instead of work secured / standardized phones
IMHO, client certificates would work work well here. I think Dovecot supports it
yes, but you accept them or not that's a different story than "log the MUA information"
Yes, it is a means to stop people from using insecure devices.
a client certificate hadrly makes a device secure if the device is compromised your cert is gone
So possibly a useful hint the OP may be interested in! Might well be that its the reason for learning which MUA was used?
well, "what client is used" is impossible
there is no user-agent like HTTP and even for HTTP the header is not mandatory and rqeuire it will break your web-app for anybody who cares for privacy while gain nothing
