I was really impressed with the “Install Postfix mail server and Dovecot on Ubuntu or Debian” guide, but this one seems to no longer be up-to-date and have been abandoned (errors from 2018 still not addressed in 2020). I understand that we may not always have time, but then it’s better to remove it than have people waste time with it.

Pyzor discover has been discontinued since around 2017:

# pyzor –homedir /etc/mail/spamassassin/pyzor discover
2020-09-29 11:54:59,586 (559) CRITICAL Unknown command: discover

Now I have to backtrack the installation and follow a more up-to-date version.

In reply to Alex. That is the most important part, otherwise spamassassin wont get the incoming mails at all - should be definitly added!

Also in the section "Setup Sieve filtering" you should mention the changes to dovecot's configuration in 90-sieve.conf to tell dovecot to use this new default.sieve sieve_global_path = /var/lib/dovecot/sieve/default.sieve sieve_global_dir = /var/lib/dovecot/sieve/ etc

Thanks for this guide. In the section “Configure Postfix to use Spamassassin as a filter” you perhaps ought to add the line to postfix’s master.cf that tells postfix to use spamassassin as a filter, i.e. changing

smtp inet n – n – – smtpd

smtp inet n – n – – smtpd -o content_filter=spamassassin
