They are getting out, but they are probably getting dropped somewhere
along the way.

Some mail server along the way is probably deciding that 'dman@hudson'
is not a valid envelope-from address (which it isn't) and doesn't
deliver the mail. It can't bounce it back to you either, since
'dman@hudson' isn't a valid address.

ALWAYS use valid envelope-from addresses.
