Sort of. Apparently TMDA is simply setting the return envelope to "<>"
by default in Defaults.py. Because this isn't part of an active SMTP
transaction, it isn't technically a bounce, and so Charter chooses to
view it as an attempted relay.

It sure is. It's not an obvious feature, but .tmda/config can override
the default for BOUNCE_ENV_SENDER, which solves the problem nicely.
Apparently, it's the presence of the null envelope that causes the mail
nazis at Charter to bounce the challenges.

So, adding a line like:

    BOUNCE_ENV_SENDER = '[email protected]'

to .tmda/config solves the problem neatly, without any patches to the
source code. Each message now has a valid envelope sender, which you can
then filter away or set up your MTA to bounce, as you please.
