Unsorted entries in PLIST files have generated a pkglint warning for at
least 12 years. Somewhat more recently, pkglint has learned to sort
PLIST files automatically. Since pkglint 5.4.23, the sorting is only
done in obvious, simple cases. These have been applied by running:
pkglint -Cnone,PLIST -Wnone,plist-sort -r -F
protocol pair. libspf2 is a library which allows email systems such as
Sendmail, Postfix, Exim, Zmailer and MS Exchange to check SPF records
and make sure that the email is authorized by the domain name that it
is coming from. This prevents email forgery, commonly used by spammers,
scammers and email viruses/worms.
