Sender checks

Does anyone implement a rule to check if the SMTP "mail from" match the "From" header?

If yes, how and where?

Finally what was the impact performance?

Thank you

Hi,

The following knowledge base article discusses filtering "spoofed" emails.

It contains some information regarding some message filters you could try.

Hope that helps,
