The Levels of blocking spam

Below is an advanced description of spam filters and how spam emails and legitimate mail filter down into the email delivery system:

Level 1 DMARC

At this level, we are dealing with the ISP and where MX records are going to and it gets into some pretty technical explanation. One of our engineers describes this area of email filtering as the following;

 DMARC builds upon the protection provided by SPF and DKIM by performing lookups on incoming messages at the ISP/Provider level to ensure that messages are coming from only allowed/approved mail systems. It requires checks of existing DKIM and SPF records in DNS. Anti Spoofing and Anti Phishing is the primary benefit of using DMARC.

Level 2 Spam filtering service: Proofpoint, barracuda, Mimecast, and others

This is where the first level of centralized filtering happens. The companies stated above are constantly trying to play catch up against the spammer’s latest attempts and tactics. Some companies start losing traction and we will advise that clients go to another spam filter service. This only happens every few years or even a decade, but we cannot however afford to get behind the ball and be complacent because it comes down to giving back all employees their time and also creating more security for our business customers.

Level 3 Email clients such as Outlook, Outlook Express, Apple Mail on iOS or others on Android

With Outlook, you have junk mail settings and white list settings. These spam settings are outside of a centralized solution. Outlook for example also includes a junk folder as well. This can get a little tricky because now the end-user has 2 spam folders to beware of now. One in the cloud and one locally. This can be looked at as double protection or too much protection. This is a personal decision perhaps and can be customized to fit each use case.

Level 4 Email host providers such as office 365, Go Daddy or other Imap or Pop3 clients

To add to the mix one additional layer of spam filtering service, we can look at office 365. So in Office 365 we have EOP which stands for Exchange online protection. It’s nice the Microsoft has done this because they will include algorithms that call on the latest anti-spam and anti-phishing attacks. Their are some emails that office 365 can look at and say this is obviously spam and help block it which is nice.

The Mid 1990’s: and Spam filtering solutions with Crown Computers

Before spam filtering and spam filtering software dealing with malicious email threats was a nightmare for managed service providers like us at Crown Computers in the 90’s. Spam software was available for sale in the 90’s.

However, if you didn’t buy good spam software, unwanted messages and a flurry of malicious messages were practically unstoppable and very annoying. First came software-based solutions for spam messages.

Platforms like Outlook Express, Netscape Email, and Outlook were prominent, and Exchange servers were less common in mid-’90s. Most business emails were accomplished via the POP3 and SMTP protocols. Email databases were not centralized. Mostly they were located on end-user machines, such as the case with the email clients above.
