Hi

On the new release i get a lot of spf failures that make me have to
disable spf. I tried to debug this spf rejection:

2019-12-19 11:09:33 H=mta-90-197.sparkpostmail.com [192.174.90.197]
Warning: SPF msprvs1=18256LU-Q9YGR=bounces-23293-11111@???
mta-90-197.sparkpostmail.com a.mx.olsns.net: transitioning domain of
spmailtechnol.com does not designate 192.174.90.197 as permitted sender

but spquery gives a different result:

# spfquery.libspf2 -i 192.174.90.197 -s
msprvs1=18256LU-Q9YGR=bounces-23293-11111@???
pass

spfquery: domain of spmailtechnol.com designates 192.174.90.197 as
permitted sender
Received-SPF: pass (spfquery: domain of spmailtechnol.com designates
192.174.90.197 as permitted sender) client-ip=192.174.90.197;
envelope-from=msprvs1=18256LU-Q9YGR=bounces-23293-11111@???;

but exim seems to do something wrong (it found the proper record but it
just ignored it):
