Spam E-Mail protection

About 60% of the total e-mail traffic in The Internet is SPAM (unsolicited email).

The first solution we offer is called SpamAssasin – a software that is capable of eliminating more than 98% of all SPAM messages. Its performance depends on the individual configuration, which can be tuned by each Elitehost account owner. The settings are explained in detail on the configuration page available in your cPanel.

The second solution we offer is a RBL configured in our mail servers.

RBL is an acronym for "Realtime Block List". In the case of e-mail there are distributed projects on the Internet which monitor where spam e-mail is originating from and add these to a real time list which can be checked when deciding whether to accept or deny e-mail.

Most spam on the Internet originates from two places:

- Virus/trojan infected machines which appear to be running normally to a user but are also sending spam out to the Internet at large after being fed a list of addresses/spam e-mail from a remote operator.

- Professional spam organizations. These businesses actually pay for a real connection to the Internet and then send spam out from their own systems up to any limits imposed on them by their ISP. (In a lot of foreign countries for instance ISP's have zero restrictions against spam and won't stop a spammer based on complaints).

The RBL identifies these machines by their internet address and adds them to a list that can be checked in real time by an e-mail server. If a server has been listed as a spam host the mail will be refused immediately. This means less overhead on e-mail systems and a lot less spam for end users. It also generally means less "fake" bounce messages that users receive when spam is forged to come from them.
