I'm trying to setup an SMTP service on port 587, TLS required,

What I can't understand is the following:

any AUTH options.
Correct.
smtpd_tls_security_options=encrypt mandates encryption.
No further communication will take place before TLS is established.
With smtpd_tls_security_level=may, I get what I
want:
250-AUTH PLAIN LOGIN DIGEST-MD5 CRAM-MD5
That only seems so to you.
You need encrypt if you want mandatory TLS.
