What's with the word 'REMOVE' in out e-mail addresses?

OK, I'm looking at Jeff Mirisola's User Profile and I see hise-mail address and I see the word, in caps, REMOVE in his address.I've checked my profile and I see the same thing. Can I stille-mail Jeff or do I remove REMOVE beforehand?

Don't worry, Jeff, I just used you as an example.SolidworksGeneral
