Acknowledgements

• Thank you, Lars Roenbaeck, for the following fixes:
  • Forgot to mention that sieve_before = /var/mail/sieve/global/spam-global.sieve should be added to /etc/dovecot/conf.d/90-sieve.conf.
  • Apparently, e-mail was being routed to rspamd twice. To prevent this from happening, you need to add -o smtpd_milters= below -o content_filter= in /etc/postfix/master.cf for the entry starting with 127.0.0.1:10026.
