AHEM server is an ad-hoc mail server. By ad-hoc we mean that a mailbox will be created for you as soon as
an email for your selected address reaches the server.
Others call it disposable mail or a temporary email address.
You can use any account name (local part of the email address) you want, in one of the supported domains.
The server serves the domains:
AHEM will check in an interval of a day for emails that aged over 2 hours, and if it find these, it will erase them.
So go ahead, and give it a try. Send an email to whatever@one-of-the domains above, and enter your account.
Or generate a random account.
When you send an email to an AHEM email domain,
The mailbox is created.
This way the site will send spam to your temporary email address, while your real address stays safe.
