Content filter, in Postfix terms, is everything that runs after queue and re-injects mail into Postfix after processing it, as described here: https://www.postfix.org/FILTER_README.html It's a common problem when using content filters that mails get DKIM signed twice, but not only this - other operations performed by Postfix can also be performed twice, leading to wrong results, all depending on configuration. Because of this, in my opinion (of course others may differ), you should avoid after queue content filtering - especially the type that re-injects mail using /usr/sbin/sendmail (when re-injecting mail using a separate Postfix smtpd instance listening on a dedicated port, you can turn off some double processing using options like no_milters) - and replace it by milters whenever possible. Both amavis and spamassassin can be run as milters instead of content filters, using amavisd-milter and spamass-milter (or other alternatives, there are a few spamassassin milters out there). If you run amavisd-new, it can call spamassassin code internally, so you don't need a separate spamassassin milter. You can of course use rspamd instead, or in addition to above. It all depends on how do you want to configure it. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
