Symantec Messaging Gateway 10.0.1 does not block spam comming from internal mail host
I have a setup with two scanners and one control center. The second scanner only receive e-mail from an SMTP relay in the cloud.
There is no filtering happening on the SMTP relay and I was expecting the spam filtering to be done on the second scanner, but it appears that the scanner accepts all e-mail from the relay without applying any filtering.
I have the following SMTP configuration on the second scanner :
- I only accept e-mails from the ip address of the relay on port 2525
- the ip address of the relay has been added to the Internal Mail Hosts list
According to Symantec documentation, that's how it should be done. The external relay should be listed on the Internal Mail Hosts list and spam should be filtered:
Any help would be greatly appreciated.
