[RFCI-Discuss] about 'bounces'

[Jeff Pang]

Hello,list,

Some messages sent from our mail systems to other mail sites are rejected for the reasons:

SMTP error, RCPT TO: 550 Mail from 188.com rejected because it does not accept bounces. This violates RFC 821/2505/2821 http://www.rfc-ignorant.org/


Could anyone kindly tell me why this happen and what RFC item we have breached?Thanks.
