[Gerrit Haas]

Hi Michael,

I'd like to ask, if this has already been implemented.

Currently spam is increasing in some fashion.

Thanks and cheers,
Gerrit

Hi Dirk,

No problem. For others who are interested in using SpamAssassin to tag or
even reject emails with SPF-Failures: Create a new textfile in
/etc/mail/spamassasssin/ and give it any name you like. But it must end with
*.cf. Example: spf.cf

Into that textfile insert the following two lines:

score SPF_FAIL 10.0
score SPF_SOFTFAIL 5.0

You might want to adjust the scores to your liking. Then restart
SpamAssassin and you're good to go.

Yes, that is a worthwhile addition and I will add it to the next release of
the AV-SPAM.
