The SASL-registry says "limited" for CRAM-MD5 and "common" for DIGEST-MD5, whatever that means. I know an MSA offering... AUTH PLAIN LOGIN CRAM-MD5 ...s/CRAM-MD5/OTP/ or similar in the text can't be a good idea. > 2.

Maybe s/secure/encrypted/ in this sentence is an alternative. What you really want is probably "stay away from LOGIN or from PLAIN outside of TLS", and CRAM-MD5 is still better than PLAIN LOGIN, or than SMTP-after-POP (for APOP or a plain USER PASS).
