Probably the latter - although I don't think I've touched it much since you
helped me set it up about 5 years ago.

Good point. Will do that when I get to the end.

Part of my problem is that I can't get SASL logging verbosity to the point
where I can see the passwords! If I could, that would help.
Two attempts.

I know the Base64 string is correct.
I turned up mysql logging and did another test - and no query appeared in the
mysql log! In an effort to prove to myself, I did an imap login attempt (which
also uses mysql) and the query appears in the mysql log. It looks to me as if
SASL isn't talking to mysql (but then I had the same impression it wasn't
listening to the imap server when I tried rimap too).
