Problem with syncing mail with attachments

[Britt Anderson]

I would appreciate advice on whether this is an issue correctible
within offlineimap, and if not, any suggestions for pursuing a solution.

I now receive an error message when trying to append messages from my
local to remote if they have a pdf attachment. It reports Errno 14 Bad
Address socket error.

As more background, For sometime now I have been happily using offlineimap to get my mails
from an exchange server at my university, and after using mutt to
locally refile, write, and so forth, using offlineimap to sync the
changes back. Everything has worked well until the last few days when
things would occasionally hang. It took me awhile to identify the
pattern in the messages, but it appears the problem is only with mails that have pdf attachments when I refile
them on my laptop and then try to communicate that change to the remote.
The downloading from remote to local works fine, and email without
attachments still do what I want.

Appreciate any advice. -- Some of the info and debug files follows. I
can post the entire debug output if advised. /Britt
