How can my users send or reply to email from outside of our network, using scalix as SMTP server.

If your users are on fixed IPs, you can edit /var/opt/scalix/sys/smtpd.cfg and allow relaying from their IP addresses.

And of course by default any user can relay from any IP using a valid Scalix authid & password.
Bear in mind the Scalix smtpd relay doesn't support secure authentication or SSL out of the box so you'll need a solution such as Stunnel (easy, search the forum) if you consider your users' logon credentials being sent in clear text over the wire a significant risk.

Not 100% accurate..... 
The authentication mechanism of the SMTP relay relies on SASL, as such some secure authentication mechanisms are supported.
Note the "AUTH" lines....
Of course, adding SSL or TLS using stunnel improves the situation further.
