Some ISP use this trick like antispam solution: http://wiki.apache.org/spamassassin/OtherTricks
But the wiki page says that with qmail remote server you can have some problem. And in fact i have find that qmail in some situations is unable to delivery the email in this situations. Why? Is qmail that have problem with the RFC? Or this trick the problem?
