[AMSAT-BB] HTML and MIME in Amsat-BB digests

Since the transition to the new mail system, I have been seeing a lot of HTML code and stuff that looks like encoded messages in the Amsat-BB digests:

--_000_B3913BA665604DB29F3D399BE88B4D53princetonedu_ Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: base64

I have been though the account setup menu but I find no box to check for "send mail in plain text". This was not a problem before the switchover to the new mail system. Is anyone else seeing this?
