That's not the proper "generic" way to do what you want. RFC 2606 outlines
best practices - and has for the last 9 years. If you want to use an
invalid address, use something like lid. The address you
are using would, if it does anything, cause some extra spam to flow toward
Microsoft's e-mail servers.
