Hi. I have customers who use our services on their schools, their school blocks the webmail port which is kind of annoying. I could do two things: - Enable Proxy Subdomains - Install own instance of Roundcube Isn't Proxy Subdomains a security risk? Proxy: Pro: All custom settings made in RoundCube by users will stay because there is only one instance of RoundCube running. Con: I heard they could hide their real IP address? Must be a security thing. Own instance: Pro: Up to date roundcube version, everyone can access the webmail because it's running on port 80. Con: Users must change custom settings again, they are not synchronized between cPanel instance and own instance. My customers are using webmail alot. I want to know your opinions. Proxy or custom instance?

  Isn't Proxy Subdomains a security risk?

  
  I'm going to assume here that you're referring to this message in CSF security check: Check proxy subdomains This option can mask a users real IP address and hinder security. You should disable WHM > Tweak Settings > Proxy subdomains
  You'll have to decide whats best for your environment. Those security checks suggestions are best practice suggestions.

  Isn't that a proxy subdomain?

  
  Correct. The docs may be of some use: Tweak Settings - Domains - Documentation - cPanel Documentation Or you can google this query for more advice on this topic: "access cpanel from behind corporate firewall" sans quotes.

  What is your opinion about it? Does it really affect security?
