I have a customer, that has a dinamic ip address, and sometimes he gets one that is blacklisted, so when he send and e-mail from his Isp e-mail account to some of the account at my server, he gets a bounce message that the ip address he is using is blacklisted.
Is there a way to whitelist hosts or e-mail addresses??
Thanks
