I'm running some initial setup tests as I plan to migrate from SM 4 to 5 and to a new server.  We're currently using declude to handle all of our spam filtering, but are hoping to drop the extra cost if SM 5 can provide reasonable filtering for us.

I have turned on simple spam filtering at the server level(SpamAssassin, DomainKeys, SPF, RBL).  Default rules simply add text to the subject line for low, medium and high - No messages are deleted.  On the test domain I'm working with I have a single email address which has all mail set to forward to an off-site email address at gmail.  

When spam filtering is turned on - when a message comes in and is detected as spam I see this in the logs:

21:34:21 [32012] Starting local delivery to me@me.com
21:34:21 [32012] Delivery for you@you.com to me@me.com has completed (Delivered) Filter: Spam (Weight: 52)
21:34:21 [32012] End delivery to me@me.com
21:34:21 [32012] Delivery finished for you@you.com at 9:34:21 PM    [id:4901532012]

The message is not forwarded.

When all spam filtering is turned off - when a message comes in I see this in the logs:

22:16:11 [32025] Delivery started for you@you.com at 10:16:11 PM
22:16:20 [32025] Starting local delivery to me@me.com
22:16:20 [32025] Delivery for you@you.com to me@me.com has completed (Forwarded Delivered) Filter: None
22:16:20 [32025] End delivery to me@me.com
22:16:20 [32025] Sending remote mail for you@you.com
22:16:20 [32025] Connecting to ... ETC..

22:16:23 [32025] Delivery finished for you@you.com at 10:16:23 PM    [id:4901532025]

The message is forwarded.  I know this isn't a gmail issue because you can clearly see in the logs that delivery isn't even attempted.

So this presents the following question.  As I said above I have all the spam filtering set to simply change the subject line.  Why is the message failing to forward.  The real setup I want is to have medium and high levels get deleted but to forward low with a subject change.  But I can't even forward ANY messages if spam filtering is turned on and they're marked as spam.

I've haven't found a setting to change this so that the message can be forwarded  Am I missing something

If you want to enable spam filtering and still allow all forwarding (including spam emails) then just uncheck Outgoing Blocking for each of the individual spam checks.

I did check Outgoing Blocking and it was not turned on for any of the spam checks.

Instead, support advised me to check the Forward Exclusions which were not set to allow forwarding of All Mail.

Here is how to check the Forward Exclusions setting:

Login in as System Admin > Manage > Manage domains > select the domain > select Edit > Go to the Technical Tab

There's a drop down menu with several options to allow forwarding of All Mail or only mail outside of specific spam levels, etc.

Once I corrected this mail was delivered properly.
