Exim authentication under FreeBSD

[Frank Leonhardt]

How do people do outgoing SMTP user-account authentication using Exim?

I'm talking about traditional user accounts (/etc/passwd) here, not 
glorious LDAP or SQL database virtual users. If you've not come across 
this little problem-ette, Exim does not ever run as root and therefore 
can't check /etc/master.passwd like sendmail/saslauthd can.

I don't want to reinvent the wheel, so if there's an existing 
daemon/authenticator I haven't found, I'd appreciate a pointer. Or can 
saslauthd work with Exim?

This isn't such an issue on Linux, which makes me wonder about Linux.

Thanks, Frank.
