[Mailman-Users] My mailman-users digests have bad MIME formatting

[Bob Glickstein]

(I've already reported this to the Mailman jitterbug database.)

The daily digest of mailman-users messages I receive has broken MIME
multipart structure.  One of the multipart boundaries is not correctly
nested.  Here's the structure of yesterday's digest, for example:

--132.151.1.90.9001.6311.929163771.576.10662
--132.151.1.90.9001.6311.929163771.576.10662
--132.151.1.90.9001.6311.929163771.576.10662
--__--__--
--__--__--
--__--__--
--__--__--
--__--__--
--__--__--
--__--__--
--__--__--
--__--__--
--__--__--
--132.151.1.90.9001.6311.929163771.576.10662
--__--__----
--132.151.1.90.9001.6311.929163771.576.10662--

Note that the closing "--__--__----" boundary appears outside the
subpart in which it's valid.

I'm happy to help diagnose or correct this problem in the code, but
first I'd like to know whether this is a known problem for which a fix
may already exist.

Cheers,
- Bob
