Advance Antispam Protection Advanced protection against spam, malware and phising

Have you ever thought how often do you hear the word Spam? And most of us associate the term only with junk mail. And there is actually a lot of truth in this comparison, but there is more behind Spam. Yes, the most familiar form of spam is unwelcomed messages with advertising content that are widely distributed on e-mail addresses found on the network. Besides annoying and unpleasant, often such messages can be dangerous to your security by inviting you to reveal your personal Important financial or other information.

How Advance Antispam Protection Works

There are some things that even a regular user can do in order to protect themselves from spam, the so-called antispam protection. Among these methods are:

  • Do not post your address in forums and do not sign up with it for suspicious services. To protect yourself from such messages, be careful about your email address.
  • Do not open and in no case reply to messages that you think can be defined as Spam. While responding, you demonstrate that the address is active and as a result you will be overwhelmed with more messages. So the best solution is ignoring these messages.
  • If you have opened spam message, do not open their attached files or clicked on links, included in them.
  • Be careful if you install free software because there are applications which track and send your email address to advertisers. To stop this process, uninstall such software.

The problem is that those people who send junk mail are getting more and more clever, so probably you will need some advanced antispam protection. Along these lines, it's a progressing battle to limit the spam impact. A few hosts have strict channels, that can bring about legitimate messages getting got and dismissed/disposed of, while different hosts may have free channels that permit more spam in. Finding an adjust to this is the test. We can help you with that.

Basically advanced antispam protection involves several stages (filters) so as to provide maximum security and a spammer-free-time.

To start with greylistining of the email. This is a technique for guarding electronic mail clients against email spam. Our mail exchange operator utilizes greylisting which will "incidentally dismiss" any email from a sender it doesn't perceive. On the off chance that the mail is honest to goodness, the starting server will attempt to resend it subsequen, at that time it will be acknowledged. In the event which the message is a spam, it will most likely not be retried, and spam sources which re-transmit next will probably be recorded in DNSBLs and dispersed mark frameworks. Greylisting depends on the way which most spam sources don't carry on similarly as "ordinary" mail frameworks.

After that the email is examined against the space's Whitelist. A whitelist is a rundown of individuals and addresses from whom the receiver gets emails. Messages which are from whitelisted sources go straight to the inbox without hitting the spam filters.

The email's message ID is subject to verification. All emails must have a such ID header. On the off chance that this header is twisted or missing, it is about a 100% shot the message is unwanted mail. At that point the email's size is also checked. This channel is valuable for steering messages over a fixed size.

As a fourth step is the email checking against known DNSBL records. It means DNS boycott, a rundown that can be questioned by means of DNS for specific IP addresses. The rundown proprietor adjusts the criteria for figuring out which IP addresses are on the rundown. A DNSBL or RBL as it is ordinarily known, has a rundown of IP delivers whose proprietors decline to stop the spam expansion.. The RBL as a rule records server IP addresses from ISPs whose clients are in charge of the spam and from ISPs whose servers are commandeered for spam transfer.

After that the mail is scanned against Sender Policy Framework (SPF), a hostile to fabrication arrangement making recognizing spam less demanding.

On the sixth filter of the advanced antispam protection there is a email checking for ASN. Self-sufficient System Numbers (ASNs) are all around one of a kind numbers used to distinguish self-governing frameworks (ASes). On the off chance that you know an ISP's ASN(s), you are able to utilize the ASN channel to order mail starting from it.

The following step includes email checking for RDNS. The Reverse DNS channel examines an IP address for a hostname. In the event in which one doesn't exist, there is a great possibility the message is junk mail.

Here the email is examined against the RHSBL's. A "RHSBL" is an abbreviation for right-hand-side boycott, a rundown that can be questioned by means of DNS for specific space names. The rundown proprietor launches the criteria for figuring out which areas are on the rundown.

In this filter the email checking goes for legitimate nameserver's. This is a server in charge of giving an area's name administrations. This channel looks into the sender's space, obtains its nameserver's IP locations, and make a check on those addresses against the DNSBLs recorded in your DNSBL channel.

Of the penultimate stage is the email content checking. The content scanning checks emails for particular substance in the headers and message assortments.. A "bogon" is a term related to an unallocated IP address. Any message guaranteeing to have started from a bogon is a conspicuous fraud and can be securely dismissed. The "header" channel searches for clear fashioned headers and other indications of spam. Mail got by this channel is more likely than not spam. The "telephone" channel looks through a rundown of spammers' phone numbers in messages. Mail which contains such telephone numbers has a high likelihood of being spam.

At the end, the email scanning is done by the so called Bayesian filter. This filter is used clssify mails as spam and non-spam by a statistical analysis of a message's headers and content . Bayesian filter can learn from classifications and corrections of users. Bayesian scoring is in scale grom 0 to 10. Lower results tend to produce more false positives while higher outcomes tend to reduce accuracy.
