Sendmail features and specs

• Established Reputation
  Sendmail has been in operation since the early days of email, providing a solid foundation and reliability in Unix-based email systems. Its long-standing presence indicates a mature and well-understood system.
• Highly Configurable
  Sendmail offers extensive configuration options, allowing administrators to customize their setup to accommodate complex email routing and handling requirements.
• Open Source
  As an open-source software, Sendmail offers transparency in its operations, enabling community contributions and adaptations to specific needs without licensing costs.
• Wide Compatibility
  Sendmail is compatible with a variety of email standards and protocols, which facilitates integration with different email systems and services.

Possible disadvantages of Sendmail

• Complex Configuration
  The extensive configurability of Sendmail comes at the cost of a steep learning curve; its configuration files are complex and can be challenging for beginners.
• Security Concerns
  Historically, Sendmail has had several vulnerabilities, partly due to its complexity and pervasive use. It requires diligent updates and security management.
• Less User-Friendly
  Compared to more modern solutions, Sendmail lacks a user-friendly interface, making it harder for less technically inclined users to manage and configure.
• Performance Limitations
  Sendmail can be less efficient than some modern mail transfer agents in terms of resource usage and performance, especially in high-volume environments.

sSMTP features and specs

• Lightweight
  sSMTP is a minimalistic SMTP client that is significantly lighter than most full-fledged mail transfer agents (MTAs). This makes it ideal for systems with limited resources.
• Easy Configuration
  sSMTP requires minimal configuration to send emails. Configuration is typically straightforward and involves editing a single file.
• Secure Email Sending
  sSMTP supports TLS/SSL, allowing for secure email transmission which is essential for protecting sensitive information.
• Simplified Use Case
  Designed purely for forwarding emails to a mail hub, reducing complexity for specific use cases like sending system alerts or reports.

Possible disadvantages of sSMTP

• Limited Functionality
  sSMTP lacks advanced features found in full MTAs like mail queuing, multiple email server support, and local email delivery.
• Unmaintained
  The sSMTP project is no longer actively maintained, which can lead to potential security risks and compatibility issues over time.
• No Authentication Handling
  sSMTP does not handle email authentication beyond basic username and password; it does not support modern authentication mechanisms like OAuth.
• No Receiving Capability
  sSMTP is incapable of receiving and storing emails, limiting its use to just sending outgoing mail.
