wrong.  ;o)

You cannot do this.  I looked into this myself.  They have to remain open
that way for Exchange email to work.

It's a RFC.

Subject: Disabling telnet sessions to ports 25, 110...

Hello,

How do I disable a telnet session to ports 25 and 110 (i.e., get "Connection
Refused"  when attempting this) on my Exchange 5.5, SP4 box? The machine is
running NT 4.0, SP6. Some companies do this purposely, others leave it open.
Obviously, I don't want to stop mail from coming in to the org, but I would
prefer not to allow telnet sessions to the box itself. Currently, my
exchange server has relaying prohibited for POP3 users. The firewall in
front only allows ports 25, 110, and 443 (for secure OWA) in to the server.

Please advise,

Jim Barr
