Anti-spam refers to methods that detect e-mail messages that are unsolicited, malicious or illegal. A spam filter is used to detect spam and divert it to a spam folder (junk mailbox).
The service entails the quarantine of spam emails. Users of this service will have the option to release these spam emails selectively. Additionally, users can add in their good/bad senders listings to better manage their emails. Missed spam that went direct to users’ mailboxes should be reported to IITS Help Centre so that the spam filtering policies can be tightened to tackle missed spam.
The vast majority of internet attacks start with an email. To get an idea of how important it is to talk about email security, Verizon pointed out, in a 2018 report, that nine out of every ten infection attempts using malware on the web happen via email. And what is one of the main tools used by cybercriminals to spread malware and other types of threats? If you thought about spam campaigns, you got it right.
You should be alert and prepared to fight different types of threats. In a company’s case, an infection or data breach can cause huge losses. Not to mention that receiving large amounts of junk email ends up directly interfering in the productivity of the team, who waste a lot of time interacting with useless and even dangerous messages.
And how to protect yourself and protect your business? This is where anti-spam filters come in. They make the first line of defence against unwanted emails. There are two main categories of filters: content-based filters and list-based filters.
