Log Message:
Update to 2.65. From the changelog:

* Fixed warnings caused by Python v2.6 (using hashlib, removing
    mimify, etc.)
* Deprecated QP_REQUIRED option as this is more than likely no
    longer needed and part of what triggered Python warnings
* Fixed unicode errors in certain post headers
* Attempted to incorporate Debian/Ubuntu patches into the mainstream
    release
* Support img type enclosures
* No file locking for SunOS
* Gracefully handle missing charsets
* Friendlier and more useful message if sendmail isn't installed
