I can't figure it out ,even like my isp. They already moved the entire domain to another server, but the problem remains.
I use sendmail in my cgi-script on the domain barbamama.com to send order confimations to clients. Most of the send messages returns with 550-Verification failed.
Till a week ago everything works fine for severeal years. I've never had any problems with sendmail. It seems that the server blazecast6.rdns.net could not be verified by the receiving mailserver ???
Pls any suggestions ??? I'm stuck
A message that you sent could not be delivered to one or more of its
