Routing restrictions Exchange 5.5
Have an interesting problem. Currently have our exchange server locked down so that no one can route mail from outside the internal network. Now we are setting up remote monitoring PC's that are using the internet to send alerts. But obviously that will not work since they are outside the internal network. Inputting IP info for each machine is not desired as there are over 300 machines that will be doing this and their addresses may change. Looking for a means that these computers can authenticate to the server. This is something that can be inserted into the code of the software sending alerts. But I am not seeing a sure fire way to accomplish this. So to sum it up, exchange server is locked down so no system outside the internal network can route mail. Need to find a way that certain systems that are outside the internal network can route mail thru our server using some sort or authentication that is hard coded into our software. Or any other means that anyone can think of.

Why not just use Blat, postie etc on the remote machines? - Original Message - From: Jerry J.

RE: Routing restrictions Exchange 5.5
A few ways I can think of: 1. On the same page where one can put in allowed IP addresses you can add only clients that authenticate. This, however, would require any POP/IMAP clients using these servers to have to change their settings. 2. If it is a static set of addresses that are otherwise external to your org add the domain(s) of those addresses to your routing tab as inbound and have CRs that reroute to the address. 3. If the external machines have IPs that all reside in the same subnet, one that you do not control, have the person who controls that subnet (who would most likely by your ISP and who would likely have an SMTP server) if they can route through his box. I suppose I could come up with some more solutions if I knew the details of what these boxes are doing, who they are sending to, etc. -Original Message- From: Jerry J.

RE: Routing restrictions Exchange 5.5
Have the remote monitoring machines utilize SMTP AUTH or put a basic SMTP server on the machines doing the monitoring so they can route mail on their own. -Original Message- From: Jerry J.

We do not need an application on the remote machines for sending the e-mail alerts.

I think you'll have to figure out how to make these machines authenticate, or use a VPN.

RE: Routing restrictions Exchange 5.5
My apologies. Had to walk away before sending message. This was to the first response about using Blat from Andy. We have full capabilities to send the e-mails. I put the smpt server on the local machine out and the programmers do not think that will be feasible due to the many variables involved at each site. (their words exactly) So it looks like I am stuck with trying to resolve this on the exchange server with something that they can hard code into our remote software. _ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin:[EMAIL PROTECTED]

RE: Routing restrictions Exchange 5.5
Thanks Chris, I do believe that it exactly what I am needing to do. Now I have never touched it before so if I set this up on my exchange server and they hard code the account and password into the software, how will that affect internal users using Outlook? I am assuming that they will need to have this account and password entered into they outlook profile somewhere. I just do not want to put out a change and bring our e-mailing to a halt. _ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin:[EMAIL PROTECTED]
RE: Routing restrictions Exchange 5.5
Not sure how your environment is configured, but in mine it doesn't effect internal users at all. None of my internal users use SMTP... Well, there is the Mac guy, but his client is already configured to use SMTP AUTH with his own NT credentials. Adding one or one hundred more user accounts wouldn't effect his ability to relay though. -Original Message- From: Jerry J.

RE: Routing restrictions Exchange 5.5
Doesn't your internal network accept internet mail in some way? How do people address mail to your company? 1. Many ISPs allow SMTP AUTH'ed mail from outside, you could have your monitor machines send mail to your ISP's SMTP AUTH server. 2. You could set up your own SMTP relay that only relays to your Exchange server AND only if AUTH is valid and then allow exchange to accept mail from this relay. -Kevin -Original Message- From: Jerry J.

RE: Routing restrictions Exchange 5.5
Another thought: Set up an internal box with a SMTP daemon. Run it on a port diff. from 25 (12345 or something equally unlikely). On your firewall map all inbound requests for port 12345 to the IP of that internal box. As an added measure use AUTH just in case some wiseguy finds the port on your border. -Original Message- From: Jerry J.

RE: Routing restrictions Exchange 5.5
Well it looks like what I am going to do is set up distro lists for each site and send the mail to the list then have anyone that needs to get the alerts on the list. Sucks for me. Alot of administration. But I plan to set up a server to automatically do this for me in the future since all information is located on a SQL server. Thanks for the info tho. As always I am learning more and more about exchange. _ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin:[EMAIL PROTECTED]
