pyzor --homedir /etc/mail/spamassassin discover
mkdir /etc/mail/spamassassin/.razor
sudo razor-admin -home=/etc/mail/spamassassin/.razor -register
sudo razor-admin -home=/etc/mail/spamassassin/.razor -create
sudo razor-admin -home=/etc/mail/spamassassin/.razor -discover

nano /etc/mail/spamassassin/99_pyzor_razor.cf
    use_pyzor 1
    pyzor_options --homedir /etc/mail/spamassassin
    pyzor_path /usr/bin/pyzor
    use_razor2 1
    razor_config /etc/mail/spamassassin/.razor/razor-agent.conf

systemctl restart spamassassin.service

Ok, seem there is some step that have been forgotten :


yum install perl-Razor-Agent pyzor
pyzor --homedir /etc/mail/spamassassin discover
mkdir /etc/mail/spamassassin/.razor
razor-admin -home=/etc/mail/spamassassin/.razor -register
razor-admin -home=/etc/mail/spamassassin/.razor -create
razor-admin -home=/etc/mail/spamassassin/.razor -discover
cd /etc/mail/spamassassin/
wget "http://sourceforge.net/projects/ixhash/files/latest/download?source=files" -O iXHash.zip
unzip iXHash.zip
mv iXhash-1.5.5/ .iXHash
rm iXHash.zip
mkdir /var/spool/spamassassin
chown popuser /var/spool/spamassassin

systemctl restart spamassassin.service

Then, you can check it by

echo "messagetext" | spamassassin

The problem is that, only seem work if the global antispam server is enable, not the individual mailbox filter....

we implemented this without iXHash Plugin on some servers and the detection rate has improved.

Ok but it's work also if each clients have is own filter (individual filter enable)?

 

[moswak]

What do you mean exactly ?
The server-wide spam filter is always activated. The settings for a single email address only refer to the number of points and white / blacklist.

these instructions are only available in german, but are said to have led to improvements in many of them.

[sebgonzes]

In this post : Plesk: Global bayes spamassassin with pyzor, razor and iXHash

=> Make sure you have activated “Switch on server-wide SpamAssassin” spam filtering and deactivated “Apply individual settings to spam filtering” in your Plesk Panel (Tools&Settings > Spam Filter Settings).

so it's work only when there is the global configuration, not the individual confiuguration

I'm not sure if that makes a difference.
here it would be good if someone from plesk said about it.
as you can see, this issue has not been considered by anyone since 11.2019.

@IgorG can you help us about this?

 

[IgorG]

Please submit Report with expectation "Help with sorting out" and I'll forward it to developers.

Any update on this one?
Should I see the Pyzor header in messages or just use the Spamassassin rule?
