Handling Unsolicited E-Mail
We regularly receive abuse complaints
about unsolicited e-mail that our customers receive which
originates from an individual or company outside of our
network. The following
actions are recommended when dealing with this type of
mail:
- Do NOT respond to the email in any
fashion to include a request to unsubscribe. Responding
simply confirms that your e-mail address is valid
for inclusion in other unsolicited e-mail.
- Send your complaint to the "abuse"
account of the originating mail server. You can get
this information by turning on verbose (complete)
headers. If you need assistance to do this, please
contact technical support. Without the detailed header
information, the problem cannot be tracked. An exception
-- some disreputable companies will use abuse complaints
to log valid e-mail addresses.
- Most e-mail software provides
the option to filter messages. Create filters based
upon what you do not want to see and transfer that
mail automatically to the trash.
This is the preferred solution!
ShawneeLink subscribes to a national database
that looks up the originating address of the sending
server. If that server's address is in the database,
the incoming e-mail is refused. Much of that database
is made up of known locations that widely distribute
unsolicited e-mail.
In addition, we perform a small check of certain domains
known to send bulk e-mail for which we refuse the e-mail.
With spammers regularly changing providers and companies
to send their mail, catching all unsolicited e-mail
is not possible. We also have to take caution that we
are not blocking valid e-mail in an effort to block
junk e-mail.
Below is a sample of a verbose header with valid entries
from a known unsolicited bulk e-mail company and what
the information means. We read the information from
bottom to top. Reviewing header information can be difficult
when there are forged entries. In this example etracks.com
is the originating mail server and if we were to file
a complaint, the requests would be sent to abuse@etracks.com.
In this case, the recipient chose to ignore it because
of the concern that it would only validate the e-mail
address.:
This tells the mail
server where to return any undeliverable messages.

This e-mail appears
to be sent from the server itself. Had it been sent
from another location to the etracks server, we would
have seen that information first with another "Received:"
line.

The address to whom
the email was sent. May be blank and usually does not
list your email address. A common method is to blind
carbon copy the recipients which gets removed by mail
servers.

Please continue to send any abuse complaints
that originate from ShawneeLink's network to
abuse@shawneelink.net. We will need the complete header
information to research the problem.
