## What it is
Swaks is a scriptable, transaction-oriented SMTP test tool written in Perl, often called the Swiss Army Knife for SMTP. It supports SMTP, ESMTP, and LMTP with extensions like TLS, authentication, pipelining, PROXY, PRDR, and XCLIENT, and runs as a single standalone script on any system with Perl.

## Use cases
- test smtp server is accepting mail
- send test email from command line
- debug smtp authentication and TLS handshake
- verify mail server responds to LMTP
- script smtp transaction tests
- check if smtp server supports pipelining or XCLIENT

## When to choose
- you need a lightweight, dependency-free SMTP test tool that runs anywhere Perl runs
- you want to script SMTP transactions with fine-grained control over headers, recipients, and extensions
- you're debugging or load-checking a mail server from the command line

## When to avoid
- you need a full mail transfer agent or production email sending service
- you want a GUI-based email client or testing interface
- you need high-volume bulk email delivery
