Hello!
How to enable postfix spf checks? instead of spamassassin. Spoofers see efa accepting the email and wont stop. Prior I was using the external/internal_sender_access but somebody here is trying to send emails from mailchimp
.
I went to install pypolicyd-spf and was met with:
Code: Select all
Error: Transaction test error:
file /usr/bin/spfquery from install of python3-pyspf-2.0.14-8.el8.noarch conflicts with file from package perl-Mail-SPF-Query-1.999.1-1.eFa.el8.noarch
Looks like some spf application is already there and I can run spfquery from command but how to get that into postfix?
thank you

Ah a package conflict. I'll need to make a custom package for eFa you can use so that it doesn't conflict. Which version of eFa are you using?

Nevermind I see you are on eFa 4 based on your post.

Ah ok, thank you!
Is it possible to use the existing spfquery in postfix, or does it have to be pypolicyd-spf?

Please test this and let me know if it works:
Code: Select all
sudo dnf install pypolicyd-spf_eFa pypolicyd-spf_eFa-milter

The spfquery that is present is a perl version, the one that comes with pypolicyd-spf is a python version. I have created a custom rpm to create spfquery as spfquery.py instead so that they can both coexist on the same system.
