How do i prevent login outside my Roundcube installation?
By that i mean how do i stop SMTP, IMAP, POP3 etc. login and usage outside the server so that it can only be used at webmail.example.com?
My goal is not to block reciving or sending mail.
Thanks in advance.
The default port used by SMTP is 25
The default port for IMAP is 993
POP3 default port is 110
Once you know this, install the
SYS Firewall plugin
Then in the port rules, add the IP address (your local IP) that each port is allowed to access
as shown in the figure
Hope this helps you
