Usual suspect network email

The Usual Suspects is a classic movie!

The "usual suspects" refers to a group of characters in the movie who are initially suspected of being involved in a crime, but are later revealed to be innocent. The term has since been used to describe a group of people who are frequently suspected or accused of something, often unfairly or without evidence.

In the context of email, a "usual suspect network" might refer to a group of email addresses or domains that are commonly associated with spam or phishing emails. These addresses or domains may be used by spammers or phishers to send large volumes of emails, and may be blocked or flagged by email providers as a result.

Some common characteristics of a usual suspect network might include:

• High volumes of email traffic
• Unusual or suspicious email patterns (e.g. large numbers of emails sent in a short period of time)
• Domains or IP addresses that are known to be associated with spam or phishing
• Email addresses that are used to send large volumes of emails to a single recipient or group of recipients

Email providers and security software may use various techniques to identify and block usual suspect networks, including:

• IP address blocking: blocking IP addresses that are known to be associated with spam or phishing
• Domain blocking: blocking domains that are known to be associated with spam or phishing
• Email address blocking: blocking specific email addresses that are known to be associated with spam or phishing
• Content filtering: analyzing the content of emails to identify and block suspicious or spammy messages
• Behavioral analysis: analyzing the behavior of email senders and recipients to identify and block suspicious or spammy activity

By identifying and blocking usual suspect networks, email providers and security software can help to reduce the amount of spam and phishing emails that are delivered to users' inboxes.
