with great difficulty i'm afraid. users will always be able to write
their own program to cummunicate on port 110. even if u where to delete
telnet they could just download a another copy.
is their a good reason for doing this?
if u're users are not very "knowlegeable" then u could get the telnet
source code and stick in a line on code somewhere to check that the port
parameter is not 110, if it is then just print something like
"telnet: Unable to connect to remote host: Connection refused".
this could prove confusing to your users!
they could still use many other program such as nc.
