 Major Spam Filter Upgrade.
 We have
upgraded our spam filter to reject spam messages at the SMTP level
instead of sending bounces. This will not only eliminate unwanted spam
failure notices, but will also increase the chances of being removed
from spammers' mailing lists, as returning an SMTP error when rejecting
spam makes it appear that the receiving mailbox does not exist.
Legitimate senders will receive a failure notice from their SMTP server
along with a link to deliver their message and whitelist their email
address. Forcing the bounce to come from the sender's own mail server
will also reduce our server load, and make sure that only legitimate
senders receive spam notices. |
