Answer 1

Well the IP 202.108.5.113 belongs to the CNCGroup in Beijing China. If you look at the source below you will see they own the whole Class B subnet you are sending to. You are receiving the message because the receiving host is rejecting your SMTP (email) request. The gibberish underneath is your english system trying to interpret the Chinese characters that are coming back as the rest of the header.

Answer 2

The IP address you show belongs to Netease - Most probably the recipient's server is not accepting emails from your domain (or your email provider). Probably this may be a spam filtering or sender filtering put in place (manually or automatically) by the recipient's system. Sometimes this may be temporary and may be caused by a spammer operating from your network (due to an automatic black-listing of your email server). The following is the full message:

"This address or the sending server is listed on our "black list" of senders, or is on the black list of one of the spam filter lists we used to reduce the amount of Spam our users receive. You should have the owner of this address or the server contact us if they have questions. "



I would recommend that you try sending the email from another email account or try sending the email after some time.

Answer 3

The number beginning with 202...is the IP to which you sent the e-mail. The message may actually mean nothing at all. Try re-sending the message after awhile. Sometimes, I've re-sent a message as many as five times before it goes through.

Answer 4

what's interesting is, the other day I got one of those, and by the time I got down to the bottom, to find out who's mail had come back, it wasn't anyone I knew, it was a dang sp*am..

Answer 5

I think it means you sent it to an invalid adress.

Answer 6
