On a 5.0 threshold (or lower), that is an obvious problem.  I've raised
the FROM_OFFERS score to a flat 5.0 here, but that's out of a 9.0
threshold, so your emails would need an additional 4.0 spam points to get
flagged here.

K> So I am wondering if there will be a rewrite of this rule?

- From later emails I've seen, apparently that has already been done, or at
least is being done.

False positives among rules of this kind are inevitable. The three
solutions I know of are
1) Notify the development team, so they can improve the rules in later
versions (via bugzilla is probably the best approach).
2) Sign up with a service like BondedSender.com or Habeas.com and balance
out the "may be spam" score with a "almost definitely not spam" score.
3) Make sure emails from your domains are included in the primary corpus,
so the score determination process run at the beginning of each version's
official release does its best to avoid false positives from your
domains.

A fourth approach is to "register" your domains with a distributed
whiltelist similar to William Stearns' blacklist at
http://www.stearns.org/sa-blacklist/sa-blacklist.current -- that will
need to be a whitelist which uses the whitelist_from_rcvd parameter,
which then requires a reliable reverse DNS lookup, if I understand it
correctly.

That whitelist doesn't yet exist, but shouldn't be hard to put together,
especially if it deals specifically with those domains like yours
subject to problems with more general domain rules.
