Local Mail Relay

RChadwick
I'm not sure if Sophos UTM can do this, but I'm guessing it's easy if it can. Regardless, I haven't been successful...

I have a network with a number of devices (Network management cards, UPS's, etc) that want to send email, but have no way to send credentials. Is there a way to configure the UTM to forward unauthenticated local email to a remote email server that does require authentication?

Thanks!

    Do you have a Mail Protection subscription?  If so, then just add the allowed IPs to 'Host-based relay' on the 'Relaying' tab and fill in the 'Smarthost settings' at the bottom of the 'Advanced' tab.  Does that do what you need?

    Cheers - Bob

    I'm not using any mail protection whathsoever. Is it still possible to do this?
    Thanks!

    If you can enable the SMTP Proxy, then you just need what I said.

    Thanks again for the response. I had a bit of trouble getting it to work. Eventually I believe I found the problem. My mail server requires authentication, and forces encryption. When I enable 'This Smarthost requires authentication', no email is sent. However, if I disable it, email does send. Before this, I configured my email server to not need authentication for sending email from an external IP to a local email address. I think that when I enable smarthost authentication, it is somehow incompatible with my server settings. I left my email server settings as-is as a temporary workaround.
