Sorry for taking so long to respond.    Here's the patch, attached.
It's been tested against the Postfix 2.3/2.4 series, but not the 2.5.x
"non-production"/development series.    People have reported success
on Postfix 2.4.6+.     I'm not sure that it'll get accepted for the
stable series, and I need to clean it up for 2.5 (which changed the
dovecot xsasl plugin somewhat).    I'll try to work on getting it
integrated, since there seems to be some interest and no one else has
submitted a better/any_other patch.
