Well, Wietse implemented the SMTP reply filter, and I implemented
the SASL mechanism filter, so, not surprisingly, each of us just
happened to recall the feature that he personally built. :-)
In this instance, I "lucked out" and the SASL-layer filter happened
to be the more direct solution.

Feature: smtp_sasl_mechanism_filter restricts what remote
SMTP server mechanism names the Postfix SMTP client passes
on to the SASL library. Victor Duchovni, Morgan Stanley.
Files: smtp/smtp.c. smtp/smtp_sasl_glue.c, smtp/smtp_sasl_proto.c.

Feature: specify "smtp_reply_filter = pcre:/file/name" to
replace remote SMTP server reply lines before they are
parsed by the Postfix SMTP client. This a last-resort tool
to fix inter-operability problems. See examples in the
postconf(5) manual page. File: smtp/smtp_chat.c.
