IMC and Demand Dial Up

[Andy Thompson]

I am trying to set up a small network with Exchange and Proxy on the same
box. The users all have E-Mail accounts provided by the ISP. I need for
the IMC to be able to POLL the ISP for the accounts e-mails that are
established on the net and deliver them to the appropriatte local account.
How is this done?

Also, how do I specify which account to use when an external e-mail account
must be used to send a message that is destined for the internet. Or is
this scenario at all possible? What if there are multiple accounts? Is it
an alias that needs to be assigned?

Any help much appreciatted?

The procedure you mention is not without it`s share of frustrations. Actually, it`s a huge pain.
Implementation isn`t all that hard, but keeping it stable is. If you can, set up another machine
to run the Internet E-mail gateway and have it dial the ISP on another phone line for mail. Having
it go through the proxy creates some funky, time consuming problems which will cost you much
more in your time than plunking down for a low end box running NT WS (or 98 if you don`t
mind have to reboot twice as often) You won`t need the IMC, just have the gateway dial-in
for downloads and uploads of the mail for your users, then install the Internet Mail
Enhancement Patch on their exchange/outlook clients and point the POP3 and SMTP
addresses in the client config back to the IP address of the gateway machine/server.

If you want the POP3 downloads to forward directly into their exchange E-Mail boxes,
you can do this as well. I`ve tested a bunch of these kinds of apps and the
"best" (or at least the most intuitive and "rockin") are the "Beamer" products at the
following URL http://www.dataenter.co.at/ . PopBeamer is a nice one. It will download
all of your user`s incoming Internet mail from their respective Pop3 mailboxes at the ISP
and route it to their appropriate local exchange mailboxes. You`ll see how easy it is
(with this product, and no, I don`t work for them) to configure the app to do this. And, you`ll
still have to figure out how to upload messages to the ISP. Depending on the version
of Exchange server, it`ll be either be A) possible from the app or B) requiring third party
add ons to make the config work.

To open up another big can of worms, consider transferring your incoming and outgoing
mail via SMTP. It`ll still be no fun with a dial up account, but you won`t have to
spend as much time creating new user accounts and getting your ISP to create more
Pop accounts on his side.

Get ready in any case for a very busy phone line... You`ll also spend a serious amount of time
configuring and supporting this thing - whatever you estimate in time, multiply it
by three. You can find some good how to docs at www.winproxy.com and an article
which will REALLY help you out is at http://www.stepconsulting.com/ptmug/faqproxyserver2.asp .


Good luck !

Thanks for the help, POPBeamer was exactly what I needed. I installed it and it worked flawlessly. I appreciatte the help. I saw an article in MCP Magazine from August 98 about SBS nightmares with Exchange, this could have been my story. It turns out that ETRN wasn`t supported by my ISP. So, POPBeamer was a lifesaver.

Thanks again,
