Exchange IMF traps internal emails

We have some system events that trigger emails from one internal email address to another internal email address. For instance, our UPS device self-test sends an email from ups@domain.com to user@domain.com. The Exchange 2003 Intelligent Message Filter traps the email (we have the IMF set to Archive). I have set the Connection Filter Exception to allow our email addresses and the Global Accept and Deny to allow our IPs under Accept, but occasionally the filter traps those emails. Am I missing a setting? TIA Roger

Thanks. We'll let you know when a new response is added.

Are you finding those messages in the UceArchive folder?
- Take a look at message headers – is it originating from an IP address that has been added to the Global Accept List?
- Is that IP address on the internal SMTP servers list as well? (The same IP address should not exist on both these lists).
- Is Connection Filtering enabled on the SMTP Virtual Server?

One way to get around this is to create an additional SMTP Virtual Server using a different IP address (you may need to add one to the network card’s TCP/IP configuration first), and not enable antispam filters on it, including IMF. You can restrict connections to that SMTP VS only to trusted/internal IP addresses.

You can also enable/disable filters for different IP addresses that a SMTP VS is bound to. In other words, if a SMTP VS is listening on more than 1 sockets (unique combination of IP address + port), you can have filtering enabled on one, and disabled on the other one.
