Spamassasin Filter not working

Hi

I have a dedicated Server with root access.

• CENTOS 6.7 x86_64 standard – exl
• WHM 54.0 (build 21)
• spamd 3.4.1
• exim-4.86.1-2.cp1154.x86_64

From 31st March onwards I noticed the incoming mails did not have the X-Spam headers.
When we looked at the Spamassasin logs it seems the mails were not filtered through Spam Assasin at all after 31st March.

I have double checked in Server Configuration - Tweek Settings "Enable Apache SpamAssassin™ spam filter" is set to on.

In Exim Configuration I have set Apache SpamAssassin™: Forced Global ON [?] to On to make sure Spamassasin is enabled for all users. In Cpanel for users it is showing as enabled for all.

We have restarted spamd and exim services a number of times and they are working fine.

Here I would like to add I made the following changes to Exim on 31st March but I don't think theses would have caused Spamassassin Filter to be bypassed. These changes were made to prevent outgoing spam, and to prevent spoofing for outgoing mails.

Changes made on 31st March
1. EXPERIMENTAL: Rewrite From: header to match actual sender [?] - Set to Remote.
2. I implemented these custom settings to prevent for Authenticated spoof mails for outgoing mails. This is working. Now outgoing mails get rejected if the sender account and the email address are different.

I had taken backups of exim configuration files on 21st March and before making these changes on 31st March 2016. I restored both of these configurations, restarted exim, and spamd but still Mail was not going through the Spamassasin Filter.

Any ideas what else I can check ?


Thanks

Update : I have created a ticket about this with Cpanel Support. They are looking at it.
I will update this thread about the outcome.

 

Update - Problem is resolved and Spamassassin is checking mails again.
Here is a quote from the Cpanel Support person, on what was done to fix it.
