The REDDOXX Spamfinder is based on various defence methods such as black- and whitelisting, advanced RBL, automatic checks of sender and recipient address, syntactical spam recognition and many more.
The combination of these conventional and proven filtering methods alone ensures the extremely high antispam factor of around 98 percent.
Every user can view the filtered e-mails and, in the event of a false positive, can set the filter itself.
Virus infected mails are already filtered out in advance by the REDDOXX virus protection.
To ensure effective protection against unwanted e-mails, including newsletters, REDDOXX has developed and patented the CISS technology (Confirmation Interactive Site Server).
The principle behind this is that previously unknown senders, to whom no e-mails have been sent so far, must first qualify themselves before their message is actually delivered: The sender automatically receives an e-mail with a verification link.
Only after successful verification will the e-mail be delivered to the recipient.
