How to accept "self-sent" messages from specific servers.

Category: General

Solution ID: 00000218

Summary:

I have PerfectMail configured to reject "self-sent" messages. But I have a server where I need to allow this. How can I block "self-sent" messages but still accept them from my local server?

Answer:

A "self sent" message is an e-mail message originating from outside your organization, where the "from" and "to" addresses are the same. Spammers set the "from" address to match the "to" address in an attempt to spoof the "from" address and side step spam filtering, usually due to white-list settings.

Normally this sort of activity would be "unusual" and a high indication of spam. However, this may not be true if your users work remotely and send their e-mail from servers located outside of your organization.

To block "self-sent" e-mail log into the Web Administrator interface and navigate to Filters > Filter Settings > Sender Tab, and enable "Block self sent e-mail".

To allow "self-sent" e-mail from a particular server, either:

1) White list the sending server or domain in Filters > Sender > White List tab; or
2) Disabling the "Self Sent" anti-spoofing test on Filters > Filter Settings > Sender Tab.
