I just tried a 5MB attachment.

Does it also sometimes fail for smaller attachments? I just wonder if
this is a size or timing issue.

The above error message from Dovecot says that the connection was closed
during the APPEND. Offlineimap should not be able to do that (I stress
"should").

Ah, OK. But could you enable imap-log instead of imap-debug? I always
find the latter a bit hard to parse...

If there's nothing to see, the rawlog utility should tell you what
happens before the connection gets closed.
