1&1 Postmaster

At 1&1, it is our top priority to carefully evaluate incoming e-mails and provide ongoing protection against unsolicited e-mails. This section provides both users and administrators with all the information they may need on the subject of e-mail and spam protection.

Unsolicited e-mail advertising causes substantial economic damage. For example, spam leads to additional costs for e-mail system operators when they are forced to invest in more powerful hardware to handle the increased volume of e-mail. Individual users of the e-mail systems can suffer major damage as well. The removal of unsolicited e-mail can waste valuable time. Sometimes even important e-mail can be incorrectly filtered out by spam filters (false positives), causing it to be overlooked and deleted along with the spam.
