MailHog is an open source email testing tool that allows developers to test their email sending and receiving capabilities more efficiently. It is a lightweight and easy-to-use tool that can be run on multiple operating systems, including Windows, Linux, FreeBSD, and macOS. By Salman Ravoof.

MailHog works by setting up a fake SMTP server on the developer’s local machine. The developer can then configure their web application to use MailHog’s SMTP server to send and receive emails. This allows the developer to test their email functionality without having to send emails to a real server.

MailHog provides a number of features that make it a valuable tool for developers, including:

  • Easy to set up and use: MailHog can be installed and configured in just a few minutes. It does not require any external dependencies, and it can be run on any operating system that supports Go.
  • Web-based interface: MailHog provides a web-based interface that allows the developer to view all of the emails that have been sent and received by MailHog. The interface also allows the developer to search for emails and to view the contents of emails.
  • SMTP server emulation: MailHog emulates a real SMTP server, so the developer can test their email functionality without having to send emails to a real server. This can help to prevent problems with spam filters and blacklists.
  • SMTP server logging: MailHog logs all of the SMTP traffic that it handles. This can be helpful for troubleshooting problems with email delivery.

Overall, MailHog is a powerful and versatile tool that can help developers to test their email functionality more efficiently. Good read!
