Package: spfmilter
Severity: important
Due to the way start-stop-daemon works, it is impossible (or at least
very difficult) to specify a useful -g option from the init script with
spfmilter. The start-stop-daemon program prevents arguments from being
properly quoted when specified in /etc/default/spfmilter, because it
does its own parsing of arguments, based upon whitespace.
The -g option specifies a default SPF record for domains which specify
none. SPF records normally contain spaces.
I have included a patch workaround with this report.
This could probably also be fixed with a patch to start-stop-daemon.
