1. XToMe is language independent.
   Spam filters filter through text in a particular language. Spam, will not be withheld in a strange language by the filter.
2. XToMe has no folder where "possible" spam can be held.
   Because filters are not 100% trust worthy a folder is created where "possible" spam can be held. This can be maintained manually by the user. This is difficult, irritating and demands precious time and concentration.
3. XToMe require no additional instructions.
   Filters expect you to indicate on a regular basis what you wish to receive and not receive.
4. XToMe does not clog up.
   Most filters clog up after a while especially when they are learning. Therefore they become inaccurate and slow.
5. XToMe lightens workload when your e-mail address has been abused.
   Should a spammer send spam using your e-mail address then XToMe will stop all undelivered e-mail. A filter will not do this!
6. XToMe limits the risk of infection with viruses considerably.
   Spamfilters pass more viruses.

100% spam detection Really all spam. Back to index

100% pass of desired mail (zero false positives) Not one e-mail will be accidentally mistaken for spam. Regardless of the contents. Back to index

Folder "possible spam" There is no folder "possible spam". User is relieved of the boring and time consuming search of this folder. User can't activate or load viruses through a beautiful website that is recommended in an e-mail. Back to index

Language independent Sooner or later a filters clog up especially if they support different languages. XToMe is language independent. Back to index

Fuzzy filter technique With XToMe it's obvious why an e-mail gets blocked. With a spamfilter it's anybody's guess. Back to index

Independent of e-mail contents Even if you put a 100 times Viagra in the e-mail it will still arrive. With a spamfilter it's depends strongly on the content if it will be passed. Back to index

Detection of e-mail virus Warning to an unknown sender when his computer is infected by virus. Back to index

Prevention of virus infection E-mail and viruses are send at random. When keys are not confirmed, they won't be delivered (Spamfilter won't block them all). Back to index

Internet blacklist E-mail from known spammers will be removed immediately. Preventing sending of unnecessary keys. Back to index

Company blacklist Because of company policy/directives you can block e-mail from certain senders (individual addresses or domains) Back to index

Personal blacklist Individually you can block certain senders (individual addresses or domains). Back to index

Company Whitelist Because of company policy/directives you can pass e-mail from certain senders (individual addresses or domains) Back to index

Personal Whitelist Every e-mail sent to a new e-mail address will be added to this list. The receptioned can send an e-mail unobstructed back. Back to index

Import e-mail addressbook By importing the e-mail addresses from the addressbook of your e-mail program in your personal whitelist the e-mails of these people will be passed through without the need to confirm a key. Back to index

Mailer Identification The assurance that an e-mail is sent by the real sender. Abuse of identity is excluded. Back to index

Spoofing protection Abuse of your e-mail address can not affect you. Back to index

External warning If an e-mail address of a sender gets abused, XToMe will notify the sender. Back to index

Cloacking technique By sending a key your address will not be revealed. Back to index

Computer load Spamfilters have to scan every e-mail for specific characteristics, XToMe does not. Only the network load will increase. Back to index

Opt-In The Opt-in system is auniversal, excepted system to send e-mails (often periodical) on a large scale (newsletters, special offers). It means that every recipient must give permission in advance in order to be sent the e-mail. Usually that happens because somebody types in his email address on an application form on a website, or by sending a "subscribe" e-mail. XToMe has the option to support the Opt-in procedure. Senders of this kind of e-mail can be passed through, send us an e-mail and we will arrange that the sender is added to the (hidden) whitelist (This list is not assessable in the Home Edition). If however you receive e-mail from a sender and you have not given permission, sent us a complaint by e-mail. By multiple incidents we will contact the sender at which point certain sanctions will not be excluded. We have to make sure that spammers can not use this method to send spam. In the (Small) Business Edition and Enterprise Edition the system administrator can change these list. Back to index

How does XToMe work (Level 1 and 2)?

XToMe has 2 security levels;
Level 1 : Sender confirms key just once
Level 2 : Sender confirms key just once and adds the key to the name of the recepiant. (key stands behind the name)

Level 1
XToMe passes only e-mails of e-mail addresses that have ones confirmed an key. Without user intervention.

For example.
John wants to send you an e-mail but you don't know John, and he has never sent you an e-mail before.
XToMe sees John's e-mail and returns an e-mail to him along with a image, with a unique number (the key) has been placed in this image.
At this point John must confirm the number (key) by means of sending back this (number) key in the subject of an e-mail.

XToMe sees that John has confirmed the number and sends the e-mail (which was initially blocked by XToMe) to the inbox of your e-mail program. The next time that John sends an e-mail, XToMe will pass the e-mail.


Level 2
XToMe only allows e-mail accompanied by a unique key. Without user intervention.

For example.
John wants to send you an e-mail but you don't know John and he has never sent you an e-mail before.
XToMe sees John's e-mail and returns a e-mail to him along with a image. A unique number has been placed in this image.

At this point John must do two things: (for this we have a help program "Assist");

1. He must place the image-number (key) behind your name in his address book.
2. The key (number) must be confirmed by means of an e-mail.

• When a spammer uses your e-mail address in order to send spam e-mail you would normally receive a large number of e-mails in your inbox stating that these e-mail haven't been delivered. With XToMe you do not have this burden.
• XToMe only downloads the desired e-mail from the server of your internet provider. After a number of days the rest is automatically removed. With this you reduce the chances of viruses to your computer.
