Hello,
Does anyone else get noticeable discrepancies in the resulting list
of IPs based on whether you run SPF walk as root or under a regular
account? For instance, when running something like “smtpctl spf
walk < common_domains.txt > common_domains_ip.txt”, the output
file contains approximately 20% more addresses than when running it
as root. Does anyone have an explanation for such behavior? You can
try it with an example list of common domains I’ve prepared at
https://ports.mocheryl.org/tmp/common_domains.txt
