Re: [spf-discuss] SPF whitelist for all subdomains in spamassassin

2006-05-09 02:18:23

Hi,
  I am using spamassassin with postfix on Linux. I am using
def_whitelist_from_spf rules for whitlelisting popular newsletter mails

Some domains send mails with from id as a subdomain of the main domain.
for eg
someid(_at_)lists(_dot_)lexico(_dot_)com

How do I whitelist such ids ( the subdomain does not have a SPF
record )

Although this is more a SpamAssassin related question, I'll have a go at it.

The answer is, you don't (at least, not with '(def_)whitelist_from_spf').
If a (sub)domain doesn't have an SPF record, you can't use that for
whitelisting since the check for its SPF record is guaranteed to be
inconclusive at best. Instead, you should 'whitelist_from'.

You can't re-use the SPF record from the parent domain, if that's what you
meant to do. SPF doesn't work that way.
