Back

[Documentation]:

# dnf install -y pyzor
# pyzor --homedir /etc/mail/spamassassin/pyzor discover
# pyzor --homedir /etc/mail/spamassassin/pyzor discover
Make the servers file readable by all
# cd /etc/mail spamassassin/pyzor
# chmod a+r servers
Run a check -
# echo "test" | spamassassin -D pyzor 2>&1 | less
You should see some output like this

Add the following lines to the end of /etc/spamassassin/local.cf
pyzor_options --homedir /etc/mail/spamassassin/pyzor

Make sure that pyzor is enabled in your /etc/mail/spamassassin/v310.pre file:

# Pyzor - perform Pyzor message checks.
#
loadplugin Mail::SpamAssassin::Plugin::Pyzor

And then make sure that spamassassin is going to use Pyzor as a check:

echo "use_pyzor 1" >> /etc/mail/spamassassin/local.cf

Now check to make sure it shows. Note: You will frequently show a timeout on Pyzor. This is normal - the server is very busy.

spamassassin -D --lint

And that's it.

Some more tips for Pyzor:

The default server will timeout 50% of the time. Google to find another server to use - most do NOT allow high volume servers to check against theirs. If you find some that DO allow this, please post them here for the rest of us!
