Where is the Mail Servers menu option?

[Son Dang]

This question is in reference to Atlassian Documentation: Configuring a Server for Outgoing Mail

I followed the instructions to go into the General Configuration area, but I do not see Mail Server anywhere on the left side menu. Perhaps this is a bug caused by my having restored a backup of my Atlassian Cloud trial account?

Edit: I am using Confluence Server.

Setting up and changing mail servers is a restricted function on Cloud - you can't do it.
