do you want your postfix to authenticate to other servers? if not, you
don't need smtp_sasl_password_maps.
if you need that, then you'll have to add cyrus-sasl support (keep using
dovecot for user authentication though). and last time I checked, myslq
passwords need to be stored in clear text if your cyrus-sasl accesses
mysql directly (as usual, I am ignoring unsupported patches).
once again, this map is for login:password pairs that are supplied by
your postfix to _other_ servers (not passwords that users supply to your
postfix). and in most cases, these have nothing to do with the passwords
that dovecot uses....
Ah, OK, I think this clarifies it for me. Thank you!
