To many NDR's involving relaying

[gtstangman35]

Good Morning,

I am having a problem where I am receiving many undeliverables (NDRs) do email addresses that are valid. This never happened with 5.5 but now with Exchange 2000 it seems to be overwhelming. The message is below. Any ideas?

Thanks,

Some firewalls have trouble with ESMTP (I know Watchguard does, for example). Try disabling it.

To do this open your Exchange System Manager, find your SMTP connection agreement and open the properties of it, click on the advanced tab, and click the checkmark telling it to send HELO instead of EHLO. Marc Creviere
