    Hey guys,

    My new range is not sending to big 2 (aol and yahoo) and here are the bounceback messages i got:

    SMTP service denied: "554 (RTR:BL) https://postmaster.aol.com/error-codes#554rtrbl Connecting IP: xxxxxxxxxx " received from mailin-01.mx.aol.com () while connected from mail-mxn11.xxxx (xxxxxx) to mailin-01.mx.aol.com ()

    Error: "421 4.7.1 [TS03] All messages from xxxxxxx will be permanently deferred; Retrying will NOT succeed. Seehttp://postmaster.yahoo.com/errors/421-ts03.html" while connected from mail-mxn14.xx (xxxxx) to mta7.am0.yahoodns.net ()

    From AOL postmaster:

    This error message indicates that a permanent block has been placed against your IP due to poor reputation. If you were blocked recently, clean up your mailing list and apply for a complaint feedback loop before opening a support request.

    And here's the response from Yahoo: https://help.yahoo.com/kb/SLN3436.html

    I would suggest to stop you mailing cause the IPs are permanently blocked, cleaning your email list from hard bounces and spam traps. whitelist your domain/IP, sign up for feedback loops, List of email feedback loops 2016 . Follow ISP best practice (There's a limits of how many emails you can send per hour and day, limit of the connections and limits of the messages in each connection) warm up the IPs properly with engaged data.

    I always test any ranges I get before I pay for them. That way whoever you get them from doesn't drag their feet replacing bad ones.

    I've never asked my ISPs to test the ranges cause they won't...maybe an IP broker would?...Seems another part of the game ha!
