Let us learn how to sendmail disable tls handshake. With the support of our Server management support services at Bobcares, we can give you a complete guide on the process.

Sendmail Disable TLS Handshake

When you disable the TLS handshake in Sendmail, we are effectively turning off the TLS protocol for email delivery between servers.

This implies that any email sent between Sendmail servers will not encrypt and may be intercepted and eavesdropped on by third parties.

While is some case we might need to deactivate the TLS handshake, when sending an email to a server that does not support TLS. It is better not to opt or this method.

This is due to the fact that email communications may include sensitive or confidential information, and removing TLS may expose that information to interception and compromise.

While utilizing Sendmail or any other email transfer agent, it is critical to examine the security consequences of removing TLS.

sendmail disable tls handshak: Configuration

The following are the typical procedures for disabling SSL handshake in Sendmail:

1. Firstly, Go to the Sendmail configuration file. On most Unix-based systems, the Sendmail configuration file is available in /etc/mail/sendmail.cf.

   We’ll need to open this file using an administrator text editor, such as sudo nano /etc/mail/sendmail.cf.
2. After that, find the TLS settings. In the setup file, look for the TLS settings section. This section usually starts with the term TLS.
3. Comment out the TLS settings: To deactivate the TLS handshake, include a # at the beginning of each line in the TLS settings. This disables Sendmail’s use of TLS for email transmission.
4. Save the configuration file: Once we’ve finished editing the Sendmail setup file, save it and quit the text editor.
5. FInally, restart Sendmail. Lastly, in order for the modifications to take effect, we must restart the Sendmail service. This is commonly done using the command sudo service sendmail restart.
