SSCC Members,
Effective April 18, 2007 we will be activating our spam-filtering
software, SpamAssassin, on all SSCC accounts. The vast majority
of those who use their SSCC email account have SpamAssassin activated
already, and this will save a step for new members. SSCC members
who receive their mail at SSCC (no forwards set) may opt-out of
SpamAssassin by sending a request to SSCC's
help desk.
SSCC members who forward their SSCC mail to some other non-SSCC
account will be required to use SpamAssassin.
Spam-filtering mail before forwarding it has been identified as
a campus (and world-wide) anti-spam best practice. If we forward
spam, not only are we contributing to the spread of spam, we also
run the risk of getting blacklisted by domains who receive this
spam from us. To the remote domain, it looks as though we are the
source of the spam. The remote domain then may decide to penalize
us by blocking all of our mail. This has actually happened to us
a few times.
The functionality of SpamAssassin is unchanged. For a review of
how SpamAssassin works, please see our publication, Spam
Filtering at the SSCC.
While these changes are minor from the perspective of a SpamAssassin
user, they allow us to make some major changes in how we run SpamAssassin.
This new system offers several advantages to SSCC members:
o Mail performance will improve because the new system relies on
one SpamAssassin database rather than accessing a separate file
for each user's account.
o There will no longer be inactive accounts accumulating spam in
their inboxes that never gets deleted. After the change, this mail
will go to the spam folder and be deleted after 15 days. This not
only saves disk space but also increases mail delivery performance.
o We will have the capacity to add new processor-intensive rule
sets to our SpamAssassin program resulting in less spam in your
inbox.
