Hello,
I need to block messages from the top-level domain "info". I'm able to block top level domain by addinginfo into domain list in Sender Filtering including sub-domain option. However when I receive some email from the top-level domain I have blocked I get an error:
"An error occurred while delivering mail to 'user@domain.org' on the SMTP server 'localhost'. The error code was 0x800ccc6f. Verify that the mailbox exists and that the Exchange receive connectors are configured properly."
And the email keeps on my webmail server. If I go to my webmail and delete manually the email it's come back to work fine until I receive another email from the top-level domain blocked.
This problem just happen with the option "Reject message". The option "Stamp message with blocked sender and continue processing" works fine but I need those message rejected.
Thanks
