About:
msmtp is a lightweight command-line SMTP client designed for sending email messages. It acts as a sendmail-compatible interface, allowing applications like Mutt to send mail through configured SMTP servers. Its primary value is providing secure, simple email delivery without the complexity of a full mail server.
Key Features:
  • Sendmail-compatible interface for easy integration
  • Supports TLS/SSL encryption for secure connections
  • Simple INI-style configuration file
  • Multiple account/profile support
Use Cases:
  • Configuring Mutt or other CLI mail clients to send emails via SMTP
  • Sending automated alerts or notifications from shell scripts
Alternatives:
  • ssmtp – Similar lightweight SMTP client, but msmtp is often considered more modern and actively maintained
  • postfix – Full-featured MTA, much heavier and complex than msmtp for simple client needs
