mixmaster mails sent, but not received by recipient

[Niels Larsen <bqz69@telia.com>]

I am using debian etch (testing) and mixmaster 3.0b2-3

When sending mails with mixmaster, the mails never reach their destination 
mail address.

I first run mixmaster-update --verbose, and then mixmaster.

Everything looks perfect, and the mails seem to be sent.

I have even tried sending from debian sarge, but same result.

Any clues?  :-)
