[78-L] Solution designed for bounces

[78-L Mail List]

Ron,
I was aware of all this before - you posted the explanations a few days 
ago to the list and I have had no problem with bouncing e-mails.
What I had in mind was how intentional these disturbances may be. My 
experience is that big enterprises sometimes direct their customers to 
new forms of service by making the old ones difficult to handle. Like 
withdrawing spare parts or refusing further updates.
Thanks again for your kind efforts to secure a well working 78-L.
Kristjan

SPF policy for domain verification has recently been required by Google.   Yahoo made the latest changes that caused all mail from Yahoo.com members to be bounced by other member's servers, causing the bounce count to go up for about 50 of our non-yahoo members, this caused 78-L to shut them down because the count of bounced emails sent to them.  The majority members did not experience the problem because their ISPs wisely ignored the SPF verification and did not bounce.

This is temporarily fixed, but the emails from the list longer show the From: address, so the body must show who sent it with a signature or deliberate  'from jerryB' in the body. But I will have a fix for this soon.
