 DM> Did you trying telnetting to a known public SMTP server (e.g.
 DM> vert.synchro.net) on port 25?

Ah, to the heart of my problems. 

Does a telnet client tell the recipient that it's a telnet session?

If I telnet into a mail server, (for example) why would a mail server answer a
telnet request.

I'll try it now and see.

Command line useage(?) 

C:\WINDOWS\system32>TELNET /?

telnet [-a][-e escape char][-f log file][-l user][-t term][host [port]]
 -a      Attempt automatic logon. Same as -l option except uses
         the currently logged on user's name.
 -e      Escape character to enter telnet client prompt.
 -f      File name for client side logging
 -l      Specifies the user name to log in with on the remote system.
         Requires that the remote system support the TELNET ENVIRON option.
 -t      Specifies terminal type.
         Supported term types are vt100, vt52, ansi and vtnt only.
 host    Specifies the hostname or IP address of the remote computer
         to connect to.
 port    Specifies a port number or service name.

telnet -f logfile.txt vert.synchro.net 25

C:\WINDOWS\system32>telnet -f logfile.txt vert.synchro.net 25
Connecting To vert.synchro.net...Could not open connection to the host, on port
25: 
Connect failed

Let's try BNB...

C:\WINDOWS\system32>telnet -f logfile.txt bnb.synchro.net 25
Connecting To bnb.synchro.net...Could not open connection to the host, on port
25: 
Connect failed

C:\WINDOWS\system32>dir logfile.txt
 Volume in drive C is Dad
 Volume Serial Number is EC35-5AD1

 Directory of C:\WINDOWS\system32

08/04/2005  05:43 PM                 0 logfile.txt
               1 File(s)              0 bytes

Is this whole thing telling me that MY port 25 is closed?

Are ports two way? Maybe closed one way but open the other way.

I'll try other ports...

Stay tuned more boring crapp after a word from your sponsor...
