What is FakeSMTP?
FakeSMTP is a free, open source SMTP test server written in Java that allows software developers to test sending emails from their applications without actually sending the messages over the internet through a real SMTP server.
Some key features of FakeSMTP include:
Lightweight and easy to install - just a single .jar file with no dependencies
Implements SMTP and ESMTP protocols for realistic testing
Spins up an SMTP server on localhost that captures messages instead of relaying them
Allows email sending to be tested during development without sending actual emails
View, edit or delete messages that were "sent" to the FakeSMTP server
Compatible with any programming language/email library that supports SMTP
Helpful for testing email functionality in applications or during continuous integration
Because FakeSMTP runs locally and simulates an SMTP server, developers can test email sending from their code without needing access to a real SMTP server. This makes it easy to test applications that send automated emails. The emails get intercepted by FakeSMTP rather than actually being delivered.
