This is an integer version of the Spamassassin score (the normal
score multiplied by 10).

See #28.

Different from other DEFAULT_* settings this should also affect existing lists.

See #13

Closes: #26

These messages are also triggering the Exim header syntax check, see #25

It was reported that the forwarding done by packages.debian.org breaks
SPF checks as there is no sender rewriting implemented. This is a workaround
for that bug in the forwarding system.

Fixes #22

Spamassassin considers dnswl.org already.

Prerequisite for enabling SPF checks in exim.

This list was actually migrated already, so the appearance here was
a mistake.
