The most likely culprit is actually Net::DNS, which has had a large number of substantial updates in recent years and for which we may well cite an outdated minimum version. There is also a difference between "Mail::SPF::Query" (obsolete but supported) and "Mail::SPF" (more robust) so you may want to check which one of those you're using. -- You are receiving this mail because: You are the assignee for the bug.
