At my last job, I put together a nice flowchart of all the UCE
restrictions we had in place for internal documentation geared toward
the reasonable competent admin who had limited knowledge of Postfix
specifics. The flowchart included the actual UCE parameter, whitelist,
or RBL; the exact error message produced; the action (mail rejected,
mail delivered, mail bounced, restriction bypassed, etc); and what
happened next in the flowchart.

The result was a four-page long Visio document (tabloid-sized paper) to
hang on the wall. Any (common) smtpd error message that my replacement
was likely to see could be identified and traced for troubleshooting.

That's not exactly the format you're looking for, but it's pretty
close. I'll try to get in touch with my old team and see if they still
have it. It might be useful documentation to add.
