MailHog is a simple package written in Go that acts as a mail server that captures all outbound email and puts it in a UI for you. Its GitHub repo is at https://github.com/mailhog/MailHog.
On Debian/Ubuntu systems, install the golang-go package using apt.
On EL-based and other systems, follow the instructions at https://go.dev/doc/install
Once you’ve got Go installed, simply run the following commands:
go install github.com/mailhog/MailHog@latest
go install github.com/mailhog/mhsendmail@latestWhen finished, you’ll have a MailHog and mhsendmail executable in your ~/go/bin directory. I recommend copying the binaries over to /usr/sbin.
If you’re running PHP and want to use it, change your sendmail_path line in php.ini to read the following:
sendmail_path=/usr/sbin/mhsendmailStart MailHog by running /usr/sbin/MailHog &
You can now access the web UI at http://localhost:8025/
If you want MailHog to run automatically as a service, create this file as /etc/systemd/system/mailhog.service
