Relaying\Routing restrictions in Exchange 5.5

[Slik]

I have a question regarding relaying restrictions, I have set relaying restrictions under the Routing Restrictions tab and this has taken care the open relay issue but now none of my users can receive email from outside of our system, is this related to the fact that I set it to allow relaying for "hosts and clients that can successfully authenticate" any suggestions\help is appreciated.

If you're using Outlook Express, you need to set the option "My server requires authentication" under Tools, Accounts...

All I did was in "Routing Restrictions" I checked "Hosts and clients with these IP adresses" and left everything else unchecked and blank. This stopped spam for me.

Incidentally, I turned it back on when I was trying to troubleshoot why I couldn't email directly from my Xerox scanner to outside email addresses and in about a week's time, my ISP was on my case about massive SPAMMING! I think it's very important that people stop spamming. I don't know what percentage of bandwidth across the globe is SPAM but I wouldn't be surprised if is somewhere near 50%.

We had the same problem, you have to unselect "Hosts and clients with these IP adresses", but leave "Hosts and Clients have to authenticate." Then change the settings on your user computers to say that "my Outgoing mail server requires authentication".



Hope this helps

Well you should ensure that you have selected your domain name as inbound under your routing tab. for example if your email address is myname@mycompany.com then you should have mycompany.com as inbound under your routing tab. If you havent done this your server will not accept any inbound mail because relaying is prohibated. try it, it should work.


cheers and Allah hafiz

ahsanmir,
Thanks for the info, I do have the domain name in as accepting for inbound, and I have it set (under Routing Restrictions) "Hosts and clients that can successfully authenticate", I have tried to set it so that it is "hosts and clients with these IP addresses" but it still will not allow mail from outside of our domain.
