Thanks - is there documentation of this protocol somewhere?
Though having just now had another look at the Postfix SASL_README, it
appears it needs support for each compiled in, suggesting there are

Postfix, AFAICS, only supports the two - but I've seen references for
IRC servers talking to an irc services server called anope, which
provides SASL somehow?

I'm not following - I'm not sure we're on the same page :-(
I already have Postfix (with a Letsencrypt cert) using Dovecot SASL
(Dovecot also uses the same cert)
Or are you talking about some other kind of cert? And are you talking
about the Postfix and/or Dovecot config?

A SASL client - so eg Dovecot and Postfix could both talk to the same
Cyrus (or other - even another Dovecot) SASL server. One reason might be
to use password hash algorithms that Dovecot doesn't know about.
