We do that, with some exceptions, as we indeed get some legitimate mail
without rDNS. However, there seems to be some issue with our rule-based
engine which results in those e-mails not getting the proper 4.7.1
response that we use for missing rDNS.
Since the rule engine is lacking in other areas, too (basically we can't
express complex rules based on combinations of triggers), I intend to
rewrite it, but that's a volunteer work in my spare time, of which there
isn't that much :-)
