As in my original post, the server *returns a null auth list* before
TLS, and returns an auth indicating login support *after* TLS. If
Postfix is not recomputing (yay potential man in the middle attacks)
after TLS, then yes it's not a matter of what's been compiled in -- it's
looking at the 'wrong' features list.

Thanks anyhow, I'm using the stock Debian packages. I'd love to be in a
situation where fiddling with the source is an option. Unfortunately, I
guess it's time to evaluate other MTAs.
