Redirect to junkmail@mydomain bouncing back! (with redirect enabled)

Question

On a 10.4.7 server with mail bouncing disabled in server admin (actually spam mail is redirected to another mailbox). Worked well for months and nothing has been changed in server configuration.
Anyone with the same problem?

Answer 1

Do you want to change this in any
way? For example, do you want to have a "Tag" level
at which mail gets delivered to the recipient with a
"JUNK" tag attached and then a higher "Kill" level
where it gets redirected to the "spam@" account?
This would be very nice... Can you help me?
Thank you very much, Marco.
This is pretty simple but involves editing the /etc/amavisd.conf file by hand via the Terminal application (and a text editor - NOT Word). The following presumes you have it already set up to redirect to the required account. We just need to amend to get a separate TAG process. The following uses the Pico editor which contains on-screen help. Commands in Terminal are shown in bold text. The "sudo" command prefix executes the command as the 'root' user and may need the admin password.
First decide the scores required for the TAG and the KILL. E.g., tag at a score of 2 and kill (redirect to your spam account) at a score of 4. Adjust as required.
Open Terminal application on the server. Stop mail server, make a backup of existing file and then edit it...
sudo serveradmin stop mail
sudo cp /etc/amavisd.conf /etc/amavisd.conf.bak
sudo pico /etc/amavisd.conf
You are now editing the amavisd.conf file. To find the line we need to edit, enter "control-W" then the search string "satag2level". The following 2 lines are the ones which can be edited...
$satag2_leveldeflt = 3.0; # some comment stuff here
$sakill_leveldeflt = $satag2_leveldeflt; # some comment stuff here
For a tag at score 2 and kill at score 4, these two need to be changed to following...
$satag2_leveldeflt = 2.0; # some comment stuff here
$sakill_leveldeflt = 4.0; # some comment stuff here
Use the cursor to move, delete and insert the new text. Note the ";" after the score levels. If you make a mistake and want to start again just Exit (control-X) and respond "N" (no) when asked to save.
When happy all is OK, Exit, and confirm the save with "Y" (yes). Confirm the file name with 'return'. Restart mail services...
sudo serveradmin start mail
Send a test mail and check your mail.log to ensure everything is OK. If not, you can either stop mail services and either re-edit or go back to backup file and re-edit that...
sudo serveradmin stop mail
sudo cp /etc/amavisd.conf.bak /etc/amavisd.conf
sudo pico /etc/amavisd.conf
When all is working, have a look at the Server Admin-> Mail-> Filters screen. You will see that it now shows that Junk Mail is set to be 'Delivered', with a Tagged subject line. This is OK and is to be expected. The score on this screen is for the Tag, the killed mail (at higher score) will be delivered to your spam account.
Note that Killed mail will also get a REJECT notice (as it did before) so you will still get the bounces in your outgoing queue. If you don't want to send these bounces, edit the following line in the amavisd.conf file...
$finalspamdestiny = D_REJECT;
and change it to...
$finalspamdestiny = D_DISCARD;
That's it! Hope it's all understandable.
