Odd situation started recently whereby emails that are delivered into a maildir folder are being truncated when read. The emails are delivered via Exim and I can see the emails are complete when I look inside them. However, when viewing the emails via Thunderbird or a webmail client, they are truncated.

I've deleted the dovecot cache and rebuilt, but there's no change here. This is running on a Gentoo Linux server (Xen) with kernel 2.6.20.
Any ideas?
