I'm trying to use TLS to connect to my mail server, which has a self-signed certificate valid until 5/2009.  When The Bat! tries to connect, it gives me an invalid certificate (expired) error.

Here's the actual log:

>9/11/2008, 13:42:38: FETCH - Certificate S/N: 8AE36CE95B94872E, algorithm: RSA (1024 bits), issued from 5/12/2008 9:06:33 AM to 5/12/2009 9:06:33 AM, for 1 host(s): localhost.
>9/11/2008, 13:42:38: FETCH - Owner: US, NY, New York, Courier Mail Server, Automatically-generated POP3 SSL key, localhost, postmaster@example.com.
>9/11/2008, 13:42:38: FETCH - Root: US, NY, New York, Courier Mail Server, Automatically-generated POP3 SSL key, localhost, postmaster@example.com
!9/11/2008, 13:42:38: FETCH - TLS handshake failure. Invalid server certificate (This certificate has expired).

Any ideas?
