Hello,

I believe you'd want to use the "Deliver to Folder" filter action. EX:

Code:

save "$home/mail/$domain/$local_part/.Spam/" 660

Note the ".Spam" folder would need to exist under all accounts for this to work, so you'd need to ensure that occurs. There's a thread on that topic at:

Deliver Spam to Spam folder, globally

Thank you.

I have tested it but it didn't work with me , the mail didn't deliver at all , not to inbox or spam box ,Even when I checked the Mail Delivery Reports the email not exist

save "$home/mail/$domain/$local_part/.Spam/" 660

The Spam Box is enable and the .spamassassinboxenable file already exist and the spam box show in the email window , But when I check the email files there 3 files only (cur , new and tmp)

below the rule which I used

Code:

if ("$h_from:" contains "[email protected]")
   then
    save "$home/mail/$domain/$local_part/.Spam/" 660
  endif

Note : the exim filter work with me normal when I use another rule

Thanks

Hello,

These type of custom rules are unsupported. It's possible the custom filter rule needs to be modified further, or you did not correctly setup the filter. Can you verify the specific steps you took to add the filter and then the specific steps you took to test it?

Thank you.

Hello,

I have added my file in /usr/local/cpanel/etc/exim/sysfilter/options/ , then I enabled my new filter from Exim Configuration Manager >filters and saved

Then I have take loot at /etc/cpanel_exim_system_filter , it's show my new rule has been added normal as below

Code:

# END - Included from /usr/local/cpanel/etc/exim/sysfilter/options/attachments

# BEGIN - Included from /usr/local/cpanel/etc/exim/sysfilter/options/my_test_rule
# (Use the Basic Editor in the Exim Configuration Manager in WHM to change)
# or manually edit /etc/exim.conf.localopts and run /scripts/buildeximconf
if ("$h_from:" contains "[email protected]")
   then
    save "$home/mail/$domain/$local_part/.Spam/" 660
  endif
# END - Included from /usr/local/cpanel/etc/exim/sysfilter/options/my_test_rule

# BEGIN - Included from /usr/local/cpanel/etc/exim/sysfilter/options/spam_rewrite

Hello,

In "WHM >> Exim Configuration Manager", under the "Filters" tab, are you using a custom filter for the "System Filter File" option? If so, you'd need to add your custom filter rules to that custom system filter file itself instead of adding them as separate filter files under the options directory. There's a thread on this topic at:

Exim custom filter not working

Thank you.

Hello,

It's possible that specific rule won't work for the purpose you intend it to. It's only offered as an example submitted by another user at:

Deliver Spam to Spam folder, globally

You may want to consider reaching out to a system administrator or posting to the Exim User's mailing list for help developing a custom Exim system filter rule that does what you need it to do, as it's typically outside the scope of support we can provide:

System Administration Services | cPanel Forums
Exim-users Info Page

Thank you.

Hello,

what about if can do the purpose by different way , if there action to change the Spam static for example

Code:

if ("$h_from:" contains "[email protected]")
   then
    X-Spam-Score = Yes
  endif

OR

Code:

if ("$h_from:" contains "[email protected]")
   then
    spam_score = 100
  endif

We just need to make the email be as spam and delivered to spam folder by anyway from the exim filter , so can we control or change the spam static form the EXIM ?

I wish if anyone have information advise us

Thanks you

Hello,

Here's a thread that you may find helpful:

EXIM filter syntax issue

Keep in mind these custom filter rules are unsupported. You may want to consult with a system administrator for help setting them up if the user-submitted examples are not working the way you need them to:

I know that this is unsupported, but this is the error that appears in the exim_mainlog when trying this:

Code:

== /mail///.Spam/ <system-filter> routing defer (-1): system_filter_directory_transport is unset

So I can see the variables are not working. Also in my system the .spam folder begins with lowercase "s", but that doesn't fix the problem.

Any ideas?

Hi @stormy,

The following method is unsupported and untested, but it was provided by a customer in a support ticket and reported to address a similar issue:

1. Remove 660 from the filter line:

Code:

save "$home/mail/$domain/$local_part/.Spam/" 660

So that it looks like this:

Code:

save "$home/mail/$domain/$local_part/.Spam/"

Then, browse to WHM >> Exim Configuration Manager >> Advanced Editor and add the following entries to the CONFIG and TRANSPORTSTART sections:

SECTION CONFIG >> Add Additional Configuration Setting:

Code:

system_filter_directory_transport = custom_spam_filter

Section: TRANSPORTSTART

Code:

custom_spam_filter:
driver = appendfile
delivery_date_add
envelope_to_add
return_path_add
group = cpaneleximfilter
user = cpaneleximfilter
mode = 0660
maildir_format = true
create_directory = true

Let me know if this helps.

Thank you.

Thank you. I ended up using a simple custom SpamAssassin rule to deal with my particular problem, so I haven't tried it, but I appreciate you providing the solution. I might need it in the future.
