Lotus Domino 6 spam Survival Guide for IBM eServer
Note that the chosen action, when creating the mail rule, is
Delete,
but the
displayed action, in the Mail rules view, is
Don’t accept message
. You should be
judicious in your use of the delete action because messages are not archived:
they are deleted and cannot be recovered. Once you click OK and save the rule it
will appear in your rules view, as shown in Figure 5-3.
Figure 5-3 Rule denying mail from specific addresses as listed in rules view
Denying mail from certain domains
Since most spammers use public e-mail service domain names, you may want to
add rules that exclude e-mail from one or more public e-mail service domains.
For example, if you have determined that all e-mail you receive from domain
spamsrus.com is spam mail, you could add a rule that automatically denies all
mail from domain spamsrus.com.
Figure 5-4 Deleting all mail from spamsrus.com
If you decide at a future time that you want to accept e-mail from a specific
address at spamsrus.com, but not from anyone else there, then you could add an
acceptable address rule for that address and move it above the denying rule.
Denying self-mail
The next rule is used to avoid a fairly common spam technique that we call
self-mail. Self-mail is e-mail sent by a spammer where the
from
address appears
to be the same as the destination address. Self-mailed e-mail from the Internet is
almost always spam. Do not confuse internet mail with Notes mail. The
from
address for Notes mail is always the full Notes e-mail address, not the Internet
e-mail address. In this way we can deny self-mail from the Internet without
eliminating the ability of users to send Notes mail to themselves, which is fairly
common. Figure 5-5 shows a self-mail rule that deletes these e-mails.
