SMHEA is experiencing trouble delivering email to ANY of the following domains managed by AT&T:
@ameritech.net, @att.net, @bellsouth.net, @flash.net, @nvbell.net, @pacbell.net, @prodigy.net, @sbcglobal.net, @snet.net, @swbell.net, @wans.net
We have submitted a support request to find the root cause. AT&T is blocking ALL emails for us, therefore any membership sign-up / renewal email and even direct messages from us are bouncing. We apologize for the trouble and are planning a work-around for this issue in the mean time. We will update again when we have news. Thank you for your patience!
It appears the AT&T domains do not offer a whitelist option which would aide in delivering expected emails to you. If someone has information to the contrary please email email@example.com and we will update with instructions here.
