What is spam filtering?


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

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 value is set to 1 point.
The more spam aspects the mail shows, the more points it gets.

Packages supporting SPAM Protection:

PACKAGE SPAM FILTER
Instant Mail Yes
Instant Website Yes
Shared Linux Hosting Packages Yes
Shared MS Hosting Packages Yes
Managed Server Yes

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


The Spam Filter is not available for Exchange hosting. But Outlook 2003 has an
integrated Spam Filter which can be setup.
