Hello Forum.
We have a working setup with stunnel listening on port 465 and connecting to port 587 SUBMIT to enable SSL encrypted authentication on SMTPS connections.
It is however still possible to use Authentication on unencrypted connections on port 25 and thereby sending the login information in cleartext. We want to force our users to use the secure variant and disable authenticated connections on port 25 (omsmtpd).
Is it posible to do this with the configuration options in /var/opt/scalix/xx/s/sys/smtpd.conf?
Has anyone done this before?
I have searched the forums and knowledgebase, so far with no luck. Can anyone help me out on this?
Thanks in advance.
cheers,
Philipp
