Fixing “/usr/sbin/sendmail: No such file or directory” in Plesk

Sendmail for Linux has the same limit on outgoing email addresses as regular emails, but it does have some specificity. It is a Linux program that allows a user or a script to send email messages. If the script is managed by mod_apache (mod_php, mod_perl, mod_python, and so on), Plesk counts this outgoing message for the relevant domain. Under other circumstances (CGI, FastCGI), Plesk counts the outgoing message for the linked subscription but not for the domain.

If the option Allow scripts and users to use Sendmail is enabled in Plesk under Tools & Settings > Mail Server Settings, then a script or a user can send messages using Sendmail. We can set subscription-level constraints on outgoing email transmissions to restrict the quantity of these messages.

Steps Needed

1. Log in to Plesk: Access the Plesk control panel using the admin details.

2. Go to Mail Server Settings: Once logged in, go to “Tools & Settings” from the left-hand sidebar.

3. Enable Outgoing Email Limitations: Within “Mail Server Settings,” locate the option labeled “Switch on limitations on outgoing email messages.”

4. Toggle the Option: Enable this option by checking the box next to it.

5. Apply Changes: After enabling the option, click on the “OK” button to apply the changes.

By following these steps, we’ll manage constraints on outgoing email messages within the Plesk.
