Hello All, The other day, I tried to report a Spam that had originated from IP address 195.59.76.89 which belongs to Cable & Wireless. I sent my report to their abuse-mailbox: abuse@cw.com that is listed on their Whois listing. Instead of a proper response, I received the following error message: ------------------- abuse@cw.com SMTP error from remote mail server after end of data: host service97.mimecast.com [91.220.42.49]: 554 Email rejected due to security policies - MCSpamSignature.sa.39.3 - http://www.mimecast.com/knowledgebase/KBID10473.htm#554 ------------------- And when I tried to report this error message [not the Spam report] to their network, I received a similar error message from CW: ----------- A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: ipadmin@cw.net SMTP error from remote mail server after end of data: host service98.mimecast.com [195.130.217.59]: 554 Email rejected due to security policies - MCSpamSignature.sa.39.1 - http://www.mimecast.com/knowledgebase/KBID10473.htm#554 postmaster@cw.com SMTP error from remote mail server after end of data: host service98.mimecast.com [195.130.217.59]: 554 Email rejected due to security policies - MCSpamSignature.sa.39.1 - http://www.mimecast.com/knowledgebase/KBID10473.htm#554 ncipsupport@cw.com SMTP error from remote mail server after end of data: host service98.mimecast.com [195.130.217.59]: 554 Email rejected due to security policies - MCSpamSignature.sa.39.1 - http://www.mimecast.com/knowledgebase/KBID10473.htm#554 --------- Therefore, I like to know why Cable & Wireless does not allow incoming abuse reports come to their Abuse e-mail listed on their Whois contact. I hope to receive more information from members of this group, and possibly from Cable & Wireless as well. Thank you, Reza Farzan rezaf@mindspring.com
