I've been using 1.0rc5 since August 2nd. Thunderbird users on multiple platforms haven't had any problems saving messages to the Sent mailbox.

I know from reading release notes that the SSL proxy code in rc5 is different from rc6, but I have to admit to being leery about upgrading since it works for me.

Here's my configure command: ./configure --without-shadow --localstatedir=/var --with-notify=kqueue --with-cyrus-sasl2 --without-gssapi --without-vpopmail --prefix=/usr/local --build=i386-portbld-freebsd5.3

Thanks for your hard work! Todd
