sSMTP: Lightweight SMTP Client
A lightweight SMTP client for Linux servers to relay email through an external SMTP server
What is SSMTP?
sSMTP is a lightweight and minimal SMTP client for use on Linux servers. It lacks many advanced features of full mail transfer agents like Postfix or Sendmail, but provides the basic ability to send email messages through an SMTP server from a Linux machine.
Some key features and uses of sSMTP include:
- Enables applications, scripts, and cron jobs to automatically send email notifications from a Linux server lacking a full MTA.
- Very simple installation and configuration, with very low overhead.
- Allows fitting in emails sent from Linux around an ISP's outgoing mail server, transparently.
- sSMTP passes the email to a central mailhub for delivery, without handling queuing or other complex mail routing tasks itself.
- No dependencies or special requirements beyond a connection to an SMTP server.
sSMTP is not designed to receive incoming emails or have high performance/scalability. But as a basic tool for outbound email notifications from scripts, daemons, or cron jobs on a Linux server, sSMTP handles that purpose well with very little setup or maintenance required.
