Welcome to the 1&1 Postmaster site
At 1&1 careful evaluation of incoming emails and protection against unsolicited emails are top priority.
This site provides both users and administrators with all the information they require on the subject of email and spam protection.
Unsolicited email advertising causes substantial economic damage. Spam causes additional costs for email system operators. For example, they are forced to invest in more powerful hardware due to the increased volume of email.
On top of this individual users of the email systems can suffer major damage. Removal of unsolicited email costs valuable time. Desirable email incorrectly filtered out by spam filters (false positives) are often overlooked and deleted along with a large volume of unsolicited mails.
