Uncomplicated
now offers Spam Filtering using SpamAssassin.
Spam or UBE (Unsolicited Bulk
Email) has become a serious problem for almost
all Internet users. Many users report receiving
many times more spam than useful email addresses.
Our server scans the email looking for attributes
of junk email and assigns a score for each attribute.
If a certain score is reached, the email is labeled
as junk, and sent to you with a specific subject
line, so that you can set a filter to move or
delete the message. Your email is never read
by a person, the entire process is automated
and no one sees the contents of your email except
you.
Below are some of the common questions about
spam and spamassassin:
Q: What is "SpamAssassin"?
A: SpamAssassin is software that analyzes incoming
mail messages and attempts to determine which
are spam and which are not. When it determines
a message is spam, it marks it to be easily
filtered by your email program.
Q: How accurate is the program?
A: Testing has show it to be up to 95% accurate.
However that familiar term "your mileage
may vary" applies here. We have seen the
program work anywhere from 65 - 90% accurate
from our less than scientific testing.
Q: Does it delete spam before I see it?
A: No. For 2 reasons. The filter is not 100%
accurate. It may decide an email that you want
is spam and mark it as such. You need to be
able to see the messages marked as spam to
make sure that the occasional "false positive" is
found. Second, it lets you know how much spam
the filter is catching.
Q: What do I do with all of the spam that I
get?
A: You can create a rule in your mail program
to dump the spam into a folder, or if you prefer,
(although we don’t recommend it) to delete
the messages that Spamassassin has marked as
spam.
Q: Even though you
don’t
recommend it, can we choose to have the server
delete the mail
identified as spam?
A: Yes. You can do so in the control panel for
each user. (Did we mention we don’t recommend
it?)
Q: What do we do about "False Positives"?
A: Our control panel allows you to add a white
list for each email user. You can add as many
email addresses to your white list as you like,
and spamassassin will not filter these messages.
Q: Can we set different white lists for each
user?
A: Yes, the control panel allows each user, (or
the person assigned as your administrator) to
set the score at which the mail is filtered,
the white list, the black list, and if the mail
should be deleted or sent to the user.
Q: What does “Training” the
spam filter mean?
A: The control panel provides you with a list
of email received for each user, where they can
identify spam messages that the filter missed.
This “trains” the filter to be more
accurate by using known spam to identify new
spam.
Q: I used the training
feature and the spam filter still doesn’t
catch the exact message, why?
A: The system does it’s best to catch
spam without making mistakes. Its priority
is to get
mail that you want delivered to you. Training
the system on a regular basis will help it become
more accurate.
Q: Does the spam filter catch viruses?
A: No. Please use anti-virus software on all
of your computers, and keep the definitions
up to date.
