Is there any way (using Webmin of course) to block access to port 25 via

The SMTP protocol (go see RFC 821, from memory) is a text-based protocol
running over a TCP connection, just like FTP, HTTP and - surprise,
surprise! - telnet. What you are asking is analogous to, "Is there any way
to block cars from this private road, while still keeping it open to
cars?". . .
