patch from Mike Gerber
Two times today I have found my offlineimap to have died with this same
situation. It appears as if certain types of messages (both spam in my
situation), cause offlineimap to choke. When it does it cannot proceed.
This means that when I run offlineimap, it pulls in messages from some
folders, then it hits the folder with the bad message and dies, leaving
undownloaded mail on the server. The only fix to this problem is to find
the problem message on the server and remove it by hand. This isn't such
a huge deal for me, since I run the server, but other people have to
come to me to ask me to delete these messages, and until I do they
cannot download their email.
I have captured the output by running script during one of these
incidents, this has been attached. Additionally, I have also attach the
problematic message.
The patch seems to work for me, might need some Python wizard and better
testing, though.
fixes deb#396443
r[1] is a list. In case it contains more than one 'str' they are concatenated
using '. '. In processmessagesflags the join is tested, for savemessagesflags I
assume that it is also needed.
I have tested this and Dovecot no longer beats offlineimap
to the punch. (-:
I achieved that by keeping the renames in tmp/ until it finally does
one last rename in new/ or cur/.
fsync the Maildir file, its final directory when writing a new message.
fsync the localstatus file and its final directory when writing the
local status cache.
This should reduce duplication in the event of hardware trouble.

The attached patch adds syncing the INTERNALDATE of IMAP folders with
the mtime of messages in maildir folders.
I want this to happen, because I'm running a dovecot over the maildirs
synced by offlineimap, and that uses the mtime as the INTERNALDATE.
When using mutt to view messages I generally sort based on the received
date, which for IMAP folders is the INTERNALDATE.
Since this is the first real coding I've done in Python the patch may
need to be cleaned up some, but it's working pretty well for me. I've
added new messages to each side, and the received date has been
preserved going both ways.

Recently I've got an exception (see below) while using offlineimap.
Exception was probably caused by invalid Date header of (likely spam)

I trued to use offlineimap and found that while being quite fast on
small folders, it takes up to several minutes (of 100% busy CPU and
almost no network traffic) to sync a folder with 2000+ messages.
While looking into the code, I found why this happens.
In folder/Base.py, in method BaseFolder.syncmessagesto_copy(),
dest.getmessagelist() is called inside a loop, while being a loop
invariant. Similar thing happens in BaseFolder.syncmessagesto_delete()
for self.getmessagelist().
This causes quadratic complexity over folder size.
Moving these calls out of loops make large folder sync fast (several
seconds instead of several minutes for folder with 2000 messages on
700MHz P3).
