Question 1

How do I install Mailpit on a Linux server?

Accepted Answer

You can install Mailpit via package managers like AUR for Arch Linux, use the provided install script for direct installation to /usr/local/bin, or download the static binary from GitHub releases and place it in your PATH. The documentation details each method for easy setup.

Question 2

Mailpit vs MailHog: which is better for modern development?

Accepted Answer

Mailpit is actively maintained with regular updates and security patches, whereas MailHog is no longer developed. Mailpit offers additional features like chaos testing, real-time UI updates, and better performance, making it the preferred choice for new projects seeking a reliable testing tool.

Question 3

How can I use the Mailpit API in my automated tests?

Accepted Answer

Mailpit provides a REST API that allows you to programmatically retrieve, search, and manage captured emails. You can integrate it into CI/CD pipelines using HTTP clients to validate email content, headers, and attachments in automated testing workflows.

Question 4

Can Mailpit send emails to real addresses?

Accepted Answer

Yes, Mailpit supports SMTP relaying to forward captured emails to a real SMTP server for delivery to actual recipients. However, this requires configuration and is intended for testing purposes, not for production email sending, so it may lack advanced routing features.

Question 5

How do I set up authentication for the Mailpit web UI?

Accepted Answer

Authentication can be enabled by setting the --http-auth or --smtp-auth flags with a username and password. The documentation provides specific steps for securing both the web interface and SMTP server, including optional HTTPS configuration.

Question 6

Is Mailpit suitable for testing bulk email sends?

Accepted Answer

Mailpit can handle tens of thousands of emails and processes 100-200 per second, making it adequate for testing bulk sends in development. However, for production-scale load testing, consider tools designed specifically for high-volume email simulations.
