smtp mail and closed relay

By Stevan ·
i'm a new admin and my company has 3 locations our main location has an exchange server the other 2 locations conect to it via pop&smtp the old admin had an open relay ( not good ) however the other locations could send out mail to anyone and now that i'v closed the relay that are only able to e-mail within the company. now one of our locations is comming in via ip address and the other is comming in via VPN the location comming in via ip I set them up so the smtp is going to there ISP and it works fine. here comes the question the one that comes in via the VPN can not get to the isp's smtp address i'v tryed to get the connected via the exchange plugin but it hanges. is there a way to open the relay to there proxy server?

The way around this is,

On the outlook client at the remote locations,
in their mail account settings,

On the servers tab on the bottom, my outgoing mailserver requires authent.

Select it and put in their user name and password for the domain.

Then they will be able to relay thru your mail server.

I hope I'm understanding your question correctly - if the VPN users have email accounts on your Exchange Server, they should be able to access these accounts through the VPN connection. Then, they will be using your Exchange server to send mail, not an ISP account. There is no "relaying" involved, they will be connected to and sending email directly through your Exchange server. Your closed relay will not affect them. They will need to have their Outlook client set up to use the corporate Exchange server and use the network authentication option (as per the previous post). You might want to set them up to have the ability to work offline, as well, so that if the VPN connection is down they could still open Outlook and use their calendar, contacts, etc. Their proxy server would also have to have open ports for smtp (port 25) and pop (port 110), which it probably already has. This should solve your problem neatly. If you have any specific questions, feel free to email directly (synergy@synoffsys.com) or repost. Hope this helps!

Follow-up on my previous answer: if the VPN connection is too slow, then I'd advise setting up Outlook Web Access for these people rather than trying to use external POP accounts. OWA works very well as an email client for external users - it's a lot faster than trying to download content through a slow VPN connection. If you need help on how OWA works and how to set it up, please email me at synergy@synoffsys.com and I can refer you to numerous tech articles that are good. Hope this helps!
