[78-L] Bounces problem based on 'Policy'

Well, it looks like the problem is that a 78-L email message always says who originaly sent it in the From: header.    ISPs have been using three methods of verification that an email sender (78-L) 'is' who they say they are:   DMARC, SPF and  DKIM.  And then the sender's domain is not 78online.com, but the server sending out the email IS 78online.com, there is a mismatch.  Up to now, this mismatch has been ignored, but with the increase in spam that lies (spoofing) about the sender, the mismatch will now matter, and yahoo, aol, live.com,  hotmail.com are rejecting emails because of it.  This has been a huge problem for mailing lists for the last two weeks (since April 14, 2014).

In order to avoid bounces because of new policy rules, 78-L will have to change the way it writes the 'From:' address in the emails that it sends out to you.   

As an example, a current email header might say    From: Thomas.Edison at Love78s.com and
   also has  Reply-To: 78-l at klickitat.78online.com.

This must change, so that the From: address always says 78-L at 78online.com.  

This will cause minor  problems because a member reading the emails in their mail program can't look at the From: line to know who sent this email to the list.  I may have to force the 'sender' to appear inside the body of the email (at the top), and that change will take a little while to test.  People can still put signatures at the bottom, but I like to see who the sender at the top even before I the email.

I checked all 75 or so blacklist sites and we are not blacklisted anywhere.    So the plot thickens .....

We are verifiable.
