Problem with spam filter and SMTP proxy on 2.2

[Guest]

Hello,

I'm trying EFW 2.2 rc 3 and have the following problem:
When turning on the spam checking feature, mail going out from the mail server in the DMZ to the firewall gets filtered and rejected as SPAM.  I have tried including our domain in the sender whitelist, as well as the mail server's IP on the client whitelist, with no success.  Any ideas?

Thanks for reading!

anyone?

I guess it's a problem with the product itself (Endian). Have tried all possible combinations, and it would seem that there's a problem with the SMTP proxy.

We are having similar issues.  I looks like smtp mail traffic is allowed through the smtp proxy from the internet and then rejected when the exchange mail server tries to send a failed Delivery notification out to the sender, the firewall catches it.

  Is this a limitation of the community edition?

Thanks in advance.
