Dear Y'all - 

I've been getting my IMAP mail from Brandeis flawlessly until this
latest holiday break, now there's none.  Undoubtably I've changed
something salient (I'm always tinkering) and now my IMAP client to
them is broken.

Following is a series of version outputs:

[version 21.5; April 2001]
Gnus v5.8.8

Here's my startup.
