Mail Login Page

Hi;

I get a 404 error when I type mail.example.com. I can’t access Webmail

I am not sure what you are trying to say but this might help How to remove port 8090 from CyberPanel - CyberPanel

I want to use “http://mail.example.com/” instead of "https://example.com:8090/rainloop/ ".

also"https://example.com:8090/rainloop/ " ssl not working

First issue the hostname ssl 2 - CyberPanel on SSL - CyberPanel
