[Dovecot] errors on copying messages to sent-mail

Howdy,

In rc10 I'm still experiencing the occasional error copying mail to my sent messages folder. This is on Thunderbird 1.5.0.7 on a Mac.

My configure command:

./configure --without-shadow --localstatedir=/var -with-cyrus-sasl2 --without-gssapi --without-vpopmail --prefix=/usr/local --build=i386-portbld-freebsd5.3

FYI, Todd
