Yes, it doesn't reverse but it also tacks on the domain.tld of the server.
Or, more accurately, it tacks on the domain.tld of the interface on which
the connection was made. So if 192.168.12.2 is 'mail.domain2.tld' then
connections into it would be from 'user at domain2.tld'. Equally true if there
are other IP addresses configured to respond to mail then their domain.tld
will be used.

Ah, that explains it. I'll have to compare the source between the sql.c
plugin and the others.

The 'auxprop' concept itself? Or the SQL plugin that's called via auxprop?

Unfortunately you may be correct. Which may lead me back to using pam_mysql
via saslauthd. Six steps forward, eight steps back, it seems. Here I was
thinking it'd be more efficient to call SQL directly, but noooooooo! Yeesh.
Of course by using PAM I get stuck not being able to use challenge-response,
