Our mail server is failing to fetch SPF record for David's mails that received directly (not via -hakders ML) and the server adds the subject header. It is failing to fetch SPF record for 2ndquadrant.com. The reason might be that the envelope-from of his mails is not consistent with his server's IP address. Anyway, mails via -hackers ML doesn't suffer so, what Amit (and I) side can do by myself is one of the following. - Being careful to reply to the mails comming via the ML. - Remove the added header by hand.. And I'd like to ask David to check out his mail environment so that SPF record is available for his message. regards, -- Kyotaro Horiguchi NTT Open Source Software Center
