Hello, I'd like to bring native support for SPF in OpenSMTPD in a future release, but for this I need a bit of help to make sure my SPF resolver works fine.
I have created a repository with a standalone executable that performs the SPF lookup and checks if an IP address is allowed to send on behalf of the sending domain: https://github.com/poolpOrg/spf https://github.com/poolpOrg/spf/blob/master/README.md If you could test and report issues, it would be nice,
