Did you ever figure anything out on this ? I have some large 100mb emails that also fail in the same way

Larch is running on a third host with OpenBSD 5.1 amd64 and ruby 1.9.3.

When attempting to copy a folder from Maildir to Exchange larch will stop when it encounters large messages (around 10 megabytes?). Turning verbosity up to insane shows the following:

[10:51:52] [info] [>] copying uid 59: XXXXXXX - Training from HR Services

Larch will wait here for 30 minutes (the Exchange connection timeout value) and the attempt to copy the message 2 more times before giving up.

Any ideas? Thanks.

I could never get it to work, I ended up going through all my users mailboxes with a shell script and moving any messages over 20mb that seemed to keep everything running smoothly.

I tired the paid version of imapsync and didn't like it. I had all sorts of problems with flags
