I had a virus about a month ago, and have been removed from most blacklists, still so e-mail is getting returned. My question is how can I find out who is sending it back? The virus has been fixed, and the problem solved. I need to geet my clients e-mail working as close to 100% as possible. Is there a way to read the header that will give me this info?
Thanks
