I'm guessing that when you installed MIME::Parser you also installed Mail::Address (part of the Mail-Tools distro) which actually is the recommended way to use MIME::Lite. I'm very suprised that Mail::Address parses less well than MIME::Lite itself does, even though I did beef up MIME::Lite's fallback parsing in v3.01. Anyway, there are a few options to bypass this behaviour. You can use an approach like hugo recommended, you can uninstall or delete Mail::Address, you can add a version number higher than Mail::Address currently has to the MIME::Lite code, or probably easiest:

BEGIN{ $MIME::Lite::Paranoid=1; }
use MIME::Lite;
[download]

Which will cause MIME::Lite to bypass loading non core external modules. This mode is a little less well tested than the normal load-em-if-you-got-em approach but hopefully should still work effectively. Ill probably add a special option that disables the loading of things like Mail::Address to the next release.

Anyway, I hope this helps.
