Mail server HTTPS protection

Fred Fox

Hi

As many of you, I'm a long time user of UTM from back when it was Astaro. I used to have a login here but it's been so long since I needed help that I've lost it Slight smile

I'm now hosting my own mail server, I've experience of using MS Exchange but want to try something else.

I've played with a few Linux mailservers, iRedmail, Zimbra, Mail-in-a-box which is what I ended up with.

I have SMTP through the proxy and spam / av scanning etc. working.  Webmail and mobile is working both internally and externally, however, I've blocked HTTP/S through the firewall at the moment as I'm not sure of the best practice for HTTP/S access to protect the server. Can anyone give me any advice or pointers please?

Thank you.

    Hi Fred and welcome back!

    Use the Web Application Firewall.  There's at least one KnowledgeBase article discussing how to use it with Exchange and that should help you.  Let us know!

    Cheers - Bob

    Thanks Bob, good to see you're still about! I can't even remember my old user or email, not that worried but thanks for the offer.

    I'll take a look at the KB's 

    Yash - thanks for the link.

    Just to clarify, I'm not using Exchange, but am I safe to assume that the same practices can be used due to the use of port 443?

    Thanks.
