Hi, Do more people see random blocking from Yahoo because it claims the IP is listed on the PBL?
> 553 Mail from 46.31.53.13 not allowed - 5.7.1 [BL21] Connections not accepted > from IP addresses on Spamhaus PBL Needless to say the IP was never on the PBL (the policy blocklist you can set as an owner of ip space). Furthermore, all other MTA's on Yahoo's side were accepting mails from this IP just fine (at that time). Thanks, David Hofstee Deliverability Management MailPlus B.V. Netherlands (ESP) P.S. @Yahoo: The link in the bounce does not work. It should be https://help.yahoo.com/kb/xx-smtp-error-codes-sln26154.html -----Oorspronkelijk bericht----- Verzonden: Sunday, August 30, 2015 12:21 PM Aan: abuse Onderwerp: yahoo.com/dmta13 entered backoff mode yahoo.com/dmta13 entered backoff mode due to "553 Mail from 46.31.53.13 not allowed - 5.7.1 [BL21] Connections not accepted from IP addresses on Spamhaus PBL; see http://postmaster.yahoo.com/errors/550-bl21.html [550]" received from mta7.am0.yahoodns.net (66.196.118.240) matching /553 Mail from \d+\.\d+\.\d+\.\d+ not allowed -/ _______________________________________________ mailop mailing list [email protected] http://chilli.nosignal.org/mailman/listinfo/mailop
