Working principle of Mailprotect
E-mail is undoubtedly the top means of communication on the Internet. The number of spam messages (unsolicited e-mails) that arrive in our mailboxes increases by the day. These messages are a major thorn in every entrepreneur's side, since we all spend an increasing amount of time trying to distinguish "real" e-mails from spam. Moreover, you are at risk of accidentally mistaking those "real" e-mails for spam, thus missing important sales or appointments.
With its Mailprotect service, Combell offers the ideal solution to the abovementioned problem. Thanks to Combell's efficient technology, your mailbox will from now on be protected against unsolicited messages, but also against viruses and other attacks.
Before it gets delivered in your mailbox, your daily e-mail is scanned by our Mailprotect servers. Combell has configured the filtering level in such a way that only messages for which it is 100% certain that they are spam are blocked.
E-mails referred to as "false positives" (those are e-mails that have been blocked by the filter but aren't spam) are reduced to a minimum or are even inexistent. When the Mailprotect servers are not 100% certain about a given message, they will "tag" this message (by marking it with '[SPAM]' in the subject line of the e-mail), but will nevertheless deliver it in your mailbox.
How is your e-mail processed without Mailprotect service?
Step 1: When you send an e-mail, your Internet provider searches the location of your recipient's mail server by sending a request to the DNS servers of the recipient's domain name.
Step 2: The DNS servers answer by revealing the MX records of the recipient's domain name.
Step 3: The outgoing mail server of your Internet provider now knows to which mail server it has to deliver the e-mail and the e-mail is thus sent
Drawback: When the mail server is not available, e-mails are lost. Your e-mails are not scanned for viruses or spam.

Step 2: The DNS servers answer by revealing the MX records of the recipient's domain name.
Step 3: The outgoing mail server of your Internet provider now knows to which mail server it has to deliver the e-mail. The MX record points to Combell's Mailprotect servers. The e-mail is sent to Combell's Maildistributor server. The task of this server is to equally distribute all incoming e-mail between the different Mailprotect servers (load-balancing). It also makes sure that e-mails are queued in case the filtering servers cannot process the whole load at once (fail-over).
Step 4: The e-mail messages are scanned for viruses and spam on server level, according to different criteria (see further) by the different Mailprotect servers.
Step 5: Once the e-mail has been filtered, it is delivered on your mail server (in other words: in your mailbox).
Step 6: When Combell's Maildistributor server is not available, e-mail messages are automatically stored and are sent only when servers are available again.
Step 7: As soon as the Mailprotect servers are available again, all e-mails are automatically transmitted, so that they can be scanned.
Benefit: When the mail server is not available, e-mails are placed in a queue and are delivered as soon as the mail server is available again. Your e-mails are scanned for viruses and spam.
