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.
