[FW-1] Anti-spoofing and sendmail



Hello all,

Some quick questions on anti-spoofing and sendmail.

We were using and IDS script to send e-mail alerts from our firewall (4.1).
We recently activated anti-spoofing on the firewall's interfaces and the mail no
longer arrives.
In the fw log I noticed that sendmail was using the address of the firewalls
external interface as a source address and was therefore dropping the packets
(rule 0 - spoofing).
Anti-spoofing on the internal interface was configured with "This net", so I
created a group containing the Internal network object and a new workstation
object I created giving it the firewall's external interface IP and set this as
the "Specific" valid address.

The packets still get dropped on rule 0 - spoofing.

Does the firewall service need to be restarted for spoofing rules to take
effect?

Is there something else I'm not thinking about?

Thanks!

Michael
