The issue #3 be resolved by using msmtp as an alternative to the mail command. This approach does not require a local Mail Transfer Agent (MTA) and can send emails via an SMTP server.
Install msmtp on your system. For Debian-based distributions, you can use:
sudo apt-get install msmtp
Configure msmtp by creating or editing the configuration file ~/.msmtprc with the necessary SMTP server details:
account default
host smtp.yourserver.com
port 587
from youremail@yourdomain.com
auth on
user youremail@yourdomain.com
password yourpassword
tls on
tls_trust_file /etc/ssl/certs/ca-certificates.crt
Ensure the configuration file has the correct permissions:
chmod 600 ~/.msmtprc
Update the backup-tool.sh script with the provided code snippet.
Test the script to ensure emails are sent successfully without relying on a local MTA.
This solution ensures that the backup process can run smoothly in environments without an MTA, maintaining the reliabilityand effectiveness of your backup notifications.
