Enforce SSL

Hi!

Is it possible to enforce encrypted authentication for SMTP? Our users use Sophos UTM 9.305-4 to send E-Mails via SMTP - and we don't want them to be able to use plaintext authentication.

Thanks, Mike

    Mike why do you want to use UTM authentication to originate emails from your clients? Do you have an internal Exchange or Active Directory server?

    Cheers - Bob

    Maybe(!) you can do this via "E-Mail Protection - SMTP - Advanced" under "TLS-Settings" i think... 

    All Hosts (or domains) listet here will be forced to use tls-encryption (auth.).

    I can't try this for now, sorry.

    AFAIK no...it seems you are a paid user open a support ticket and ask.  post back with the response i could sit corrected..[:)]


    If I do that I will let you know the answer.

    Inernally we have eDirectory and GroupWise. We had problems when Users used Client -> Groupwise -> Sophos -> External with Sophos quaranting many valid messages as Spam. Therefore a Sophos Partner technician advised us to have our Clients authenticate via Sophos, the way being Client -> Sophos -> External.
