Setup a Local Only Email Server (Windows Only)

1 - Install hMailServer

In setup, select internal db engine.
Now you have a service called hMailServer and an administration program on the Windows start menu (hMailServer Administrator).

Open hMailServer Administrator program.
Click on "Domains" and then "add domain".
At "domain name" put a fake domain to test. Use "localhost.com" (without the quotes): hMailServer requires a fully qualified domain, so, we cannot use @localhost.
Make sure to add your domain (localhost.com) to hosts file: C:\windows\system32\drivers\etc\hosts

Go to "Domains", click on the created domain, and then click on "accounts", then "add account".
At "address", create your account name, here I use "rael" (without the quotes), and put a password.
Change "Administration level" to "Server".

Enabling this, you can use any email address ending with you fake domain. Example: here, my unique account is [email protected]. But while testing systems, I can use any address like [email protected], [email protected], etc, because all will be redirected to [email protected]
Open "Domains", click on your domain, open Advanced tab, fill field "catch-all address" with account created on previous step.

At Windows, you can use Windows Live Email (http://explore.live.com/windows-live-essentials-other-programs?T1=t2).
Of course, you can use any email client.
While configuring
- Incoming Server is POP3, and the username is the full email address (like [email protected]), and the password is raw text (no encrypt).
- POP3 and SMTP server are "localhost" (without the quotes).
- Outgoing server do not require authentication.
Don't use the email client and the hMailServer Administration application at the same time!
