I could certainly end up using SMTP/LMTP, but in my case I need complete 
control over when, where, and how messages are delivered. The IMAP interface 
gives me that control, but the Doveadm HTTP API seems easier and I can do 
operations that span all users with this API. So, I don’t need to worry as much 
about scaling (since I think IMAP is limited to one user at a time per 
connection).

If the Doveadm HTTP API isn’t mature enough or have a PHP interface (like 
Roundcube gives me for IMAP), I may have to just go with IMAP or SMTP. SMTP is 
a whole lot easier from PHP of my 3 options, but only handles new message 
delivery and not the other admin actions I need to do. Eventually, I want to 
hire some programmers to code my admin app in Go and move to a micro-services 
architecture, but to start out, when scaling isn’t that important, I’m coding 
the mail admin app in PHP (since Roundcube Framework gives me a lot of mail 
handling classes that are mature and well tested).
