When I try to reply to an e mail sometimes I get Reporting-MTA: dns; smtpout.karoo.kcom.com Final-Recipient: rfc822;ngoedupwangmo@sbcglobal.net Action: failed Status: 5.0.0 (permanent failure) Remote-MTA: dns; [144.160.235.143] Diagnostic-Code: smtp; 5.1.0 - Unknown address error 553-'5.3.0 alph772 DNSBL:RBL 521< 212.50.160.34 >_is_blocked.For assistance forward this error to abuse_rbl@abuse-att.net' (delivery attempts: 0)

Any ideas anybody? Reporting to abuse.....as I have done in the past produced no help whatsoever.

Yet I received an email today and 'replying' and sending a new message produces the same resuut This is not the first time this has happened and messages get through from Ngoedup and sometimes my 'replies' gets through. Thank you Bernard

Error 553 usually indicates a blocked email account or possibly a misdefined account setup (such as a discrepancy between sending email account and SMTP email account.

Thanks David still don't know why some 'replies' get through and others do not. Perhaps never will. Bernard

That may depend on receiving server security requirements. That is, mail to some recipients may always work and mail to others may always be rejected.
