How to Setup Sendmail on Kali Linux & CentOS

Sendmail is a powerful and flexible Mail Transfer Agent used to send and route emails across networks. It’s commonly chosen for its robust feature set and security-focused design.

Today, we will walk through how to install and uninstall Sendmail on Kali Linux using three different package managers and cover common configuration tips.

Why Use Sendmail?

Sysadmins trust Sendmail for its security, scalability, and broad compatibility. However, it does not include a Mail User Agent (MUA) by default, so you’ll need to use one like `mutt` or `VM`.

Some features include:

• Anti-spam protection via UCE/SPAM filters
• Support for SMTP AUTH (SASL) and STARTTLS (SSL)
• Integration with DB, NIS, LDAP, and DNS maps
• TCPWrappers and IPv6 support

The Sendmail package supports system integration and upgrades. Do not delete it unless you are replacing the entire mail setup.
