Check Box "Copy default mail message" doesn't work

[fhamumtaz]

I've made project in java for email client. And I used mercury mail server.
When I create user in "Manage Local User--add--****@localhost" but check box "Copy Default Mail Message" doesn't work, can't for checklist
Is there something wrong in my mercury?
This picture just for example

Any email *@localhost will NEVER work for top dns and routing reasons

@jobeard
Email with a star symbol was only the picture, and "fha@localhost", the actual email addresses
But the check box still can't work, I mean can't for the checklist

First off the domain name is incomplete; localhost.com. And yeah MS messed that up too. That fix is in the etc\hosts file
and change

• 127.0.0.1 localhost
• to
• 127.0.0.1 localhost.com localhost

Understand; the only system that can possible access that email will be the PC where the change is made, aka itself, nothing else on your lan

Even with this change, you will need to

1. ipconfig /flushdns
2. net stop "dns client"
3. net start "dns client"

so as to have dns resolve the localhost.com

Are you aware that this email will require a POP3 or IMAP server on this PC?
