Block outgoing emails for a user

[youds]

Hi

I'm about to release a theme and would like to offer the option to try the theme out before buying. Is there a way to restrict / stop outgoing emails for a specific user (or domain)?
I've seen this plugin: http://www.directadmin.com/forum/showthread.php?threadid=8393 but it is not for the latest SpamBlocker 3.

Can anyone help?

While I've not tested it, it looks as if it would run when added to the latest SpamBlocker release candidate.

Try SMTP blocker plugin. You can block specific domains
