of this problem.
When the email arrives at the other end, at the email addressees ISP, the email server will attempt to find a mailbox identical to the address.
If it finds one, it delivers the email.
However, if it does not find one or there is an error in the address portion of the email, it will stop delivery and send an email to the originator of the email, in this case, you.
Recently I have receiving this message for the past week. I don't remember sending e-mails to the web sites. I got about 6 of them stating mail delivery subsytem cannot send because of error. Does anybody out
there could help me on this?
