Oh, I also setup the dovecot LDA and configured exim to deliver to it so that it will write out the W= flag and updates the dovecot indexes on delivery (im pretty sure im correct here).

Thanks Brandon.

It seems I should try it out, especially given that using the dovecot LDA includes W= in the filename. I'll report back on this thread once testing is done.
