Authenticator for separate passwd-file

Hi

I have a system with exim4 and dovecot (pop3). Real users can get their
mails with pop3 and send mails over smtp. Virtual users don't exist in
/etc/passwd. They have their separate passwd-file in
/home/dovecot/passwd. Virtual users receives their mails to
/home/dovecot/users/%u and can use a pop3-client to transfer these. Its
working perfectly.

But my problem is, virtual users can't send mails over smtp. I need a
new authenticator for exim4.

So if an virtual user tries to log in (smtp), the authenticator should
use the file /home/dovecot/passwd and for a real user it should use the
normal pam-mechanism. Is that possible?

Thanks for any help.

IMO an _additional_ one.

IMO yes.
But you need a second authenticator that compares the
cerdentials handed over by the client with the entries in
/home/dovecot/passwd.
And don't forget that the user exim is running as will need to be given
read access for the password file.
