Seems to work fine for some hosts but not gmail.com or outlook.com
mail3$ smtpctl spf walk < 1 (this is gmail.com)
35.190.247.0/24
64.233.160.0/19
mail3$ ./spf gmail.com 35.190.247.3 <- in the output of spfwalk
checking if 35.190.247.3 can send for gmail.com: EXISTS: 0
EXISTS: 0
EXISTS: 0
soft-fail
mail3$ ./spf gmail.com 185.185.185.185 <- made up address
checking if 185.185.185.185 can send for gmail.com: EXISTS: 0

mail3$ ./spf poolp.org 45.76.46.201
checking if 45.76.46.201 can send for poolp.org: pass
mail3$ ./spf poolp.org 45.76.46.202
checking if 45.76.46.202 can send for poolp.org: fail

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,
