Mindspring has heavy filtering and will block all mail that
does not have reverse dns lookup to confirm the origin. I have
many Mindspring corporate customers, but in DNS transitions like
I did last week, they bounce all that mail, otherwise it flows
normally.
When they cannot send mail, I had to have these customers put my
DNS in their settings then all worked fine. Its almost like
Mindspring is disabling base addresses but not web addresses, but
this fixed it for all my customers every time.
