Default too much spam

Hi

I am getting huge amounts of spam being passed through the mail server. I have checked the incoming headers and can see that they are being spam tested, but rather than being filtered and the header re-written they are being sent straight through.

I can no longer find any way to change the spamassassin settings via the web interface, and according to the settings in the local.conf for spamassassin all mail with a score over 5 should be rewritten as spam.

As this is not happening I can only surmise that spamassassin is no longer working.

The web interface is showing that the service itself is running so there must be a configuration error somewhere.

Could you give me some ideas on where to start looking

Thanks

ispmanager version: 5.56.0-2016.05.05_12:51

More info in case it helps.

I have exim/dkim, clam and spamassassin enabled on all mail domains, and spamassassin enabled on all mailboxes.

local.conf
Code:
required_hits 5
report_safe 0
rewrite_header Subject [SPAM]

score USER_IN_WHITELIST_TO	-5000

bayes_path /var/spamassassin/bayes
This should rewrite the mail header on detected spam.

Excert from my mail log

 identified this incoming email as possible spam.  The original message
 has been attached to this so you can view it (if it isn't spam) or label
 similar future email.  If you have any questions, see
 the administrator of that system for details.
Here you can plainly see that the header is not being re-written for spam. I would like eventually to be able to set spamassassin to delete spam over a certain level but cannot risk that until I can verify that spamassassin is reading the correct configuration file.

Or is it reading the user.pref in the root .spamassassin folder?

ANY help would be good.

Sorry, ISPmanager can't configure spam assassin. But you can reconfigure exim&spamassassin as you want. Maybe some other forum users can help you with manual configuration.

RBL blocking just went from ubuntu/ispmanager

on ubuntu

root@panel:/etc/exim4# ls -la dnsbllist
-rw------- 1 Debian-exim Debian-exim 116 Jul 25 20:13 dnsbllist

file exists

root@panel:/etc/exim4# grep -r dnsbllist *
root@panel:/etc/exim4#

but exim in not aware of that

on Debian installation

-rw------- 1 Debian-exim Debian-exim 93 Feb 25 11:41 dnsbllist

file exists also, and it's reference in configuration

root@hosting0:/etc/exim4# grep -r dnsbllist *
exim4.conf.template: dnslists = ${readfile {/etc/exim4/dnsbllist}{:}}

So, You've missed something in ubuntu release

something strange, I've another ubuntu installation, where is RBL still works
and there is difference in size of exim4.conf.template

good one have

-rw-r--r-- 1 root mail 14226 May 17 15:10 exim4.conf.template

and the bad one

-rw-r--r-- 1 root mail 14051 May 17 03:11 exim4.conf.template

Looks like some "glitch" on upgrade, both ubuntus have same ispmanager version - ISPmanager Lite 5.64.1

Got good version, changed IP, looks good... question for support, do I need to check anything else (related to exim4.conf.template)?
