I have a question about email spoofing. I am using Checkpoint Firewall-1
4.0 Build 4031.
I have a rule to accept mail on port 25 (SMTP) to our external mail server
address, which
is then translated to an illegal internal address.
any email_external SMTP accept long gateway
Is there any way to set up the firewall to accept and send only incoming
mail from those employees
that have legitimate email addresses with the company? I don't want our
email server being
used as spam servers.
Sorry for the newbie question...
