I was hoping to resolve this by looking at existing threads, but nothing has helped me out. Last week I sent out some e-mails, to a couple different domains. I immediately received a message back from the one domain (mchsi.com) saying that it wasn an unroutable address. Two days later I received the same message back from an aol.com address. I have had no problem receiving e-mails in this time, and I am unaware of any system changes that could've caused this. After reading through some threads, I replaced exim.pl and exim.conf with the ones found on files.directadmin.com, but the error remains. Please let me know if you can assist me with this, or if you need additional information from me. Also, I've tried two different e-mail accounts, and the error is the same.
Thanks,
Aaron
