RE: Re: SPF Guess

Ralf,

Meng and I were originally discussing a means of using the SPF routines to
include a blacklist.  The idea was to pass a macro to the SPF 'guess'
process ("-exists:%{ir}.sbl-xbl.spamhaus.org" for example) which would
produce a fail if the IP was blacklisted.  This is no different than
implementing blacklisting at other phases of the mail transport, it is just
that I was hoping to do it with the SPF code.  In my opinion, this is no
different than the discussion about HELO checking.  They are probably best
left outside the SPF specification, but easily CAN be done by the SPF code
and can be very helpful if it does.  The "right" place is for it to be done
by other parts of the MTA.  As for using the 'local' part (explained below),
that is not something that I can do.  I was simply talking about using SPF
mechanisms and modifiers.

Ralf,

If you want to override something, just use the local option that was
already mentioned.

Can you please provide an example of that?  I'm just not understanding
what is meant....

I am using spf-milter and provide a command line argument for that.
Inside the milter this argument is forwarded to the Mail::SPF::Query object.

From the spf-milter code:

push (@extraParams, local => $opt_l);

new Mail::SPF::Query (ip => shift, sender => shift, helo => shift, 
@extraParams)

The value that I use is "include:_spf.selene.doeblitz.net", which allows
me to whitelist hosts that are allowed to forward mail to my system.
