Emails are one of the most basic means of communication in business organizations and certainly no one wants to see unwanted messages in their inbox. These unwanted messages are popularly known as spam and spam has been the biggest threat to email services ever since their inception. But how can an unwanted message be so dangerous and why is it so difficult to avoid having spammy messages in our inboxes? Read on to know everything about spam and ways spam filtering services can fight them for clean inboxes in business organizations.
Every email is either legitimate or illicit and start their journey from one email server to another. However, if either of the servers is used for illicit purposes by spammers, the message becomes a spam and makes the communication redundant for the real user on the other end. Spam is said to affect business organizations in a number of ways and cost a fortunate if not regulated. Overloading systems, clogged up mailboxes, defrauding recipients, reduction in overall productivity and draining morale are few of the security and resource risks that spam messages pose. Also, many spam messages also carry harmful viruses, malwares in them and try to infect the system they are viewed in.
That being the present situation of spam, researchers have found that the severity and frequency of spam has only increased with time and technological advancements. This is because, spammers and hackers are growing smarter and bigger every day, devising new ways to infiltrate the system and captivate regular computers and use them as zombies to spread the spam network. This is why spam filtering services have become mandatory for companies where email is the means of communication. Spam filtering services as the name suggests filter spam from real messages and constantly update themselves to outdo the smart spammers and hackers. Below mentioned are the ways spam filtering services identify spam and prevent them from entering their destined mail servers.
• Spam filtering services mainly use a mail exchange record (MX record) to prevent spam attacks. A MX record is a huge database of IP addresses that are backlisted as sources of spam messages. It acts as an interceptor between the two email-servers involved and stops the message from entering the destination server if it recognizes that the message is coming from one of these backlisted IP addresses.
• While the spam filtering services backlist a number of IP addresses, they also whitelist the credible IP addresses, whose messages can bypass the spam filters. This in turn reduces the time and resources spent on filtering each and every mail sent by a credible organization.
• A lot of new spam filters are constantly added to tackle the new ways spammers find to bypass the existing spam filters. This way, spam filtering services ensure that the destination email servers remain safe, no matter how smart the spammers get.
• The spam filters mentioned above can also be customized to suit each individual organization and include its own set of whitelisted and blacklisted IP addresses. Thus, apart from security, these services also offer flexibility and ease of use.
