eneville Posted April 20, 2005 Share Posted April 20, 2005 Hello, I have a customer who has reported to me that their mail cannot be transmitted: 220.127.116.11 does not like recipient. Remote host said: 550-Message rejected because qmail3.uk-plc.net [18.104.22.168] is blacklisted 550 at bl.spamcop.net see Blocked - see http://www.spamcop.net/bl.shtml?22.214.171.124 Giving up on 126.96.36.199. Please could someone tell me why this is, I sent a message to a host that I know has a number of RBL checks including bl.spamcop.net and the mail got through just fine.
