Well, I can try to help. In general that's what we'll all do, but we have
other things to do in our lives, too. (-:
Zeroth question: Why use virtual users rather than regular-old UNIX users?
The regular way requires much less configuration, after all!

If you do 'su - vmail -s /bin/sh' you will get a shell running as user
vmail. Run 'deliver' with the arguments it takes to deliver to a target
user; does mail get delivered?
If not, we better fix that first!

Can you turn up the verbosity from sendmail?

So it sounds like Dovecot is fine and this is a sendmail question.
We can try to help, but I don't use Sendmail (I do use Dovecot...), so
it's not clear that we'll be able to.

Reply with answers to 0 and 1 and we'll see where we can go.
People are going to scream bloody murder about that.
