What is Spam Protection?


You can define the level of Spam protection filtering in the 1&1 Control Panel.
You can choose between three levels of protection: low, middle, high or disable the filter.

When you receive an e-mail, according to the level of filtering you choose, it is categorized as
SPAM. The e-mail is then marked by adding "SPAM" to the subject line.

You can then define filter rules in your local e-mail client to sort the emails into corresponding
folders right away.

Brief explanation on how the Spam Filter works: The Spam Filter checks the mail header for things
like, forged outlook clients, date in future, the $ sign in the subject line etc. Depending on
the content, values are assigned.

For example: The $ sign is a strong indicator for spam so this values to 1 point.
The more spam issues the mail shows, the more points it gets.

Packages supporting SPAM Protection:

Instant Website YES
Shared Linux Hosting Packages YES
Shared MS Hosting Packages YES
Managed Server YES

eShops YES
Root and Windows Server YES (when using 1&1 Mail Servers)



If the Spam Protection is activated, Spam emails will be marked as SPAM. These mails can then be
deleted by a rule in your email client, sent to a specific folder and or a file.

The Spam protection becomes effective after approximately three hours. For the Spam
protection no additional costs arise.


Depending upon your adjusted level a Spam recognition program examines the headlines of the E-Mail.
If the E-Mail contains characteristics, which refer to Spam, for example words, a wrong date or the
like determined, points are assigned. These form the so-called Spam score. Depending upon height of
the Spam core the E-Mail is marked accordingly as SPAM.
