Exchange 5.5 Relay Problem

By paull ·
I have discovered that our exchange server can be used as a relay host.
I have gone through the Technet article "Is Your Exchange Server Relay-Secure". However having done the suggested, anybody using MS Outlook Express client is unable to connect to the server.
Changing everyone to use full version of Outlook is out of the question due to cost and time factors.
Any help would be Appreciated!

Go to Exchange Admin->IMS->Routing->Restrictions
there you can go different ways:
1.Check "Clients succesfully authenticate"
2.Check "Clients with these IP-addresses" and
type in IP and netmask
Then restart IMS.

Iam usually check how it works by telnet on 25th port.

Thanks for the info, however when I tried to implement the MS Outlook Express clients were not able to connect.
I am now trying to find out if there are extra config options for Express to allow it to connect when I set the server up as per your option 1.

Thanks for the help

I'm assuming you mean they can connect but can't send mail. In Outlook express goto the tools/accounts section and look at the properties of the account. On the servers tab tick the "My Server Requires Authentication" setting, you should be able to leave the settings section alone.

cheers
