Hello, same problem here. I use Thunderbird 3.0.1. The strange thing is
that with the same version of TB on my PC at home I don't have this
issue. The same TB on my work PC has this issue and only on one account
(that has Dovecot as imap server) but I have other account (some with
dovecot, other with courier-imap) where this does not happen, so I think
is TB related.
Also here no NFS, ext3.
