My ISP recently changed the configuration of its mail
servers so that it's no longer possible to forward them to Gmail to take advantage of
its huge SPAM database and have the e-mails be sent back to my
ISP.
Instead, all e-mails that are deemed SPAM
are sent to each domain's spam@ mailbox, and the ISP expects all users to sort through
SPAM using some desktop solution (I'm using POPFilter). Since SPAM represents over 90%
of the e-mails I get, it's very time-consuming to go through the SPAM folder just to
recover the very occasionnal legit e-mail
:-/
For those of you managing e-mails for ISP's
or big organizations, what are the current techniques available to filter SPAM on the
servers so that users spend as little time as possible sorting
e-mail?
Off the top of my
head:
outgoing
mail: Forbid outgoing connections with destination port TCP25 other than the ISP's mail
servers, to reduce the impact of viruses that take advantage of compromised computers to
send SPAM silently -> all outgoing SMTP connections should go through the ISP's mail
serversincoming mail: When the exact
same e-mail is sent to thousands of recipients, mv /dev/null so that the user only has
to examin the trickle of SPAM that went through the
net
Are there
other techniques that have proved to be effective at reducing the amount of SPAM users
end up seeing on their desktop?
Thank
you.
