How to configure Inbound Message Filter to reject Emails sent by "noreply@" except "noreply@x.com"

Summary:

Hello,

We have a need from the business which is related with Inbound Message Filters (thru Setup and Maintenance --> Service --> Communication Channels --> Manage E-Mail Filters).

Content (required):

How can we configure the rejection of all Emails from senders that start with "noreply@(.*)" except emails Emails from the sender "noreply@xpto.com"?

We've configured a filter which reject Emails from senders that start with "noreply@(.*)" and another filter to accept Emails from the sender "noreply@xpto.com". Nevertheless, when we sent emails from the ender "noreply@xpto.com", they are blocked / not processed.

Thanks in advance

Best Regards
