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
