VPCN: VPOP3 Connect Now
VPCN is a small utility that works in conjunction with Paul Smith's VPOP3 email program. The purpose of VPOP3 Connect Now
is to prompt VPOP3 to "connect now" and check for new mail.
We use VPOP3 in a number of business, typically with a DSL or Cable Modem connection. We set up the scheduler in VPOP3 to
check periodically for new mail every 15 to 60 minutes. The problem is when someone needs to receive an email immediately.
Let's say I need to get an urgent email message NOW! I would have to get up from my desk, go to the Server Room and unlock
the closet, turn on the monitor, find the mouse, right click on the VPOP3 icon in the task bar (if this feature is even
enabled) and prompt VPOP3 to "Connect Now", turn off the monitor, lock the closet, and return to my desk. Sound too much
like work to me.
Hence the development of "VPOP3 Connect Now". Right from my desktop I can prompt VPOP3 to Connect Now and get that urgent
email message without ever having to leave my desk. VPCN is a DOS based program and has been tested on 9x, NT, and XP.
VPCN is really is nothing more that a scripted Telnet program.
Installation consists of copying all the files in VPCN.ZIP to a location, modifying the "VPOP3 Connect Now.lnk" file, and
copying a modified "VPOP3 Connect Now.lnk" file to an appropriate location for each user.
Copy all files in the VPCN archive to a shared folder that is in the search path on the server (To check the path, from a
DOS prompt type PATH and hit enter). From there, copy the modified "VPOP3 Connect Now.lnk" file to each users desktop,
start menu, or task bar. The same "VPOP3 Connect Now.lnk" file will work for all users.
Copy all files in the VPCN archive to each users Workstation and place the "VPOP3 Connect Now.lnk" file to each users
desktop, start menu, or task bar. You may have to modify "VPOP3 Connect Now.lnk" for each user.
Modify VPOP3 "Connect Now.lnk"
If you change the installation location of VPCN you will need to modify the "VPOP3 Connect Now.lnk" file to reflect the
new location and the location of the VPOP3.ICO file in. To do this, RIGHT click on the "VPOP3 Connect Now.lnk" file and
CONNECT.TXT The text file that contains the scripting commands. Modify this file as needed.

VPOP3.ICO The little red mailbox icon.
A few notes:
1) IP ADDRESS: The IP address for our VPOP3 email server is 192.168.1.200. You will have to determine the IP address of
your VPOP3 server. To do this run:
Windows 9x WINIPCFG
Windows NT/2000/XP Click Start, Run, type CMD and hit Enter to open a DOS window, ant type IPCONFIG
Be sure to leave the 5106, as that is the default Telnet port for VPOP3.
2) Choosing a USERNAME and PASSWORD: There are a few consideration for the choice of the USERNAME and PASSWORD:
SECURITY: In our organization we placed VPCN in a shared directory on our Novell Server. The username and password used is
therefore available for all to see. If security is not an issue, this is fine. If security is an issue, you could create a
"dummy" VPOP3 user, but this would burn up one of your user licenses....
PERFORMANCE: IF VPOP3 is used in a large environment with 100's of users, prompting the server could get out of hand. One
solution would be to administer VPOP3 to use a distinct connection for each user. That way when a user prompts VPOP3 to
connect now, VPOP3 could use a connection other that "conn start 0" just for thir use.
The script to make all this run follows:
192.168.1.200 5106 <-- The IP address of your VPOP3 Server followed by the Port (default is 5106)
WAIT "(type LOGIN )" <-- Once the Telnet session starts VPOP3 send this prompt
SEND "LOGIN username\m" <-- We send a LOGIN username\m. Change the VPOP3 username as needed.
WAIT "password" <-- Wait for the password prompt
SEND "password\m" <-- Send the VPOP3 useranme's password
WAIT "help" <-- Wait for the "help" prompt
SEND "conn start 0\m" <-- Send command to start the connect number 0
WAIT "OK Connection Started" <-- Wait for the confirmation so we can
SEND "QUIT" <-- QUIT - terminate the telnet session
Please note that the same procedure can be followed from a Telnet session.
