What?  You want documentation? Ppfffffffhhhht.

Most clients list specific things like CRAM-MD5, etc.... under SMTP
Authentication,  which means "I'd probably be happy with a MDA using SASL on the
backend".  For the most part the client doesn't much care how the MDA
authenticates the SMTP stream,  so long as the mechanism is supported.

It can be,  SMTP authentication methods are determined by the MDA which often
can use SASL, a flat file, sometimes PAM (hence the linkage to libpam.so.0).
