Experiences with Sophos Puremessage auto-reply messages

[Ron Blitz <r-blitz () NORTHWESTERN EDU>]

The Northwestern University Information Technology department would like to
solicit some feedback from anyone who has had experience working with Sophos
Puremessage RBL functionality. Specifically, we are interested in your
reactions to the auto-reply feature sent back to the ISP after Puremessage
has determined that an email should be blocked due to the presence of the
sender on the blocking list. In your experience, is this auto-reply
functionality reliable and does a message reach the sender to inform them
that the email messages never made it past the SMTP server to the intended
recipients?

Thanks for your feedback on this subject.
