Description Matt Domsch 2014-01-25 10:51:59 EST
Spec URL: http://domsch.com/fedora/libspf2/smf-spf.spec
SRPM URL: http://domsch.com/fedora/libspf2/smf-spf-2.0.2-6.el6.src.rpm
smf-spf is a lightweight, fast and reliable Sendmail milter that implements the
Sender Policy Framework technology with the help of the libspf2 library. It
checks SPF records to make sure that e-mail messages are authorized by the
domain that it is coming from. It's an alternative for the spfmilter,
spf-milter, and milter-spiff milters.

All credit goes to Paul Howarth for this.  We are also actively trying to find out who is maintaining this upstream anymore, as the original author appears to have disappeared from the Internet (all addresses fail, SF account is deactivated).

SELinux policy update needed to it can open a unix domain socket to talk to sendmail, rather than listen on a TCP port.  Paul wrote this policy, which is a combination of smf-spf and another program, smf-sav.

Thanks for doing this work.  This is sorely needed.

Why does the spec file declare a dependency on sendmail?

    Requires:       sendmail >= 8.12

Our site uses postfix.  As far as I can tell, this dependency is not required.  Can you please remove it?

Comment 3 Andrew J. Schorr 2014-09-06 10:40:34 EDT
It may also make sense to add a minor patch to remove this gratuitous header that is inserted into every message:

X-SPF-Scan-By: smf-spf v2.0.2 - http://smfs.sf.net/

That seems to server no particular purpose, and the URL is not even valid any more.

There are some patches here that may be worth considering:


They remove the header and make a few other small changes.  I'm not sure whether they are all desirable, but certainly removing or at least fixing that header makes sense.

Comment 4 Matt Domsch 2014-10-01 09:56:32 EDT
I am withdrawing this packaging request, as opendmarc now implements SPF testing internally.

is the opendmarc package review.
Comment 5 Matt Domsch 2014-10-01 09:59:29 EDT
is the opendmarc package review, not 1057876.
