No. You need to configure things so that each e-mail user has a
password. The password is used for two things:

- for POP/IMAP, to read mail.

- for exim, to send mail.

Since you seem to be using a preconfigured webserver, maybe
something is already configured, or maybe there exists an
all-in one package. If your users only send mail, google
/etc/exim4/passwd

Otherwise, as I wrote earlier, you need to configure SASL. You
also need a POP/IMAP server, maybe set up a page for your users
to change their passwords, a webmail... it gets to be a lot of
work.
