The organization of which these subscribers are a member maintains an SPF record which denies access to all servers except a named few, which seems to be the cause of these problems. As a work-around I set mlmmj to use a different from address in the "From:" header. This solution is, however, plainly bad as it removes the original sender from the headers. I have seen other lists use "Sender:" header, but results are a mixed bag. With strict SPF checking of the "From:" header in place these mails also don't pass. What would be the correct solution? any help, pointers greatly appreciated. regards, Theo
