How much spam is your company sending?
July 2007
Everyone knows how big a problem receiving spam has become
for many companies, but another growing problem is the
amount of spam companies are unwittingly sending out E-mail
security vendor BorderWare says it has monitored outbound
e-mail of more than 8,000 customers in 65 countries and
discovered that on average, 80% of the mail sent out from
the customer’s domain is spam.
The reason: Spammers are spoofing these domains so that
it appears messages are coming from legitimate sources,
but they are actually unwanted e-mails. Also, enterprise
PCs are falling victim to botnets, malware that takes
over computers and turns them into spam servers without
users knowing it. This is becoming a problem for companies
because they risk ending up with bad e-mail sending reputations.
Blacklists, reputation services and other sender-rating
methods are likely to block mail sent from these domains
from reaching their recipients, according to BorderWare
officials, because many of these services look only at
the volumes of mail sent from a domain and assume high
volumes of messages mean spam.
The BorderWare
Security Network, or BSN, is a reputation service
that does real-time content inspection of e-mail messages
to get a detailed view, and factors the content of messages
into the sender’s rating, officials say.
