EX2013 - Transport rules size limits or reduce NDRs

    Question

  • Hello everybody,

    one of our customers sent e-mails on a larger scale , the database contains old / invalid entries (hard bounces ).
    This means that the server ends up regularly on a blacklist.
    He asked us if there is a possibility to stop the e-mail to " known hard bounces ".
    We're talking about 10k and more e- mail addresses.
    Question therefore: is realized with a transport rule , this according to your experience?

    How big is the space for transport rules in Exchange 2013?

    Alternatively a smtp proxy before Exchange would also be possible.
    Does anybody knows a reasonable product?

    Thanks

  • You might want to (1) obtain a high-quality message hygiene service and configure it to block that traffic, and/or (2) use some other system for bulk mailing that is better suited to that task than Exchange.

  • Hello Ed,

    if the Job can be done with Exchange and it has not a high Impact to Performance, we eill do it with Exchange.

    Otherwise we are searching for an other solution, perhaps there is an admin which has solved this right now :-)

    Best reguards
