AHEM - Ad Hoc Email is a temporary disposable email service. Its public website provides a disposable email service for the domain @ahem.email.
You can send an email to any @ahem.email address and check the AHEM mailbox to retrieve and read the email.
But AHEM is also installable as an on premise server, serving your own domains.
Setting up AHEM as your own temporary email service is now ever easier with Docker.
