mjr is partially correct about the allowed format, and completely  
correct about the fact that the e-mail address provided is incorrect.

mjr is correct that this e-mail address is not an RFC 822 compliant  
address.  However, RFC 822 is deprecated - RFC 5322 is controlling  
now.  The ABNF for the local part is:

local-part      =   dot-atom / quoted-string / obs-local-part

For purposes of this example, dot-atom and obs-local-part (which is  
the RFC 822 definition of local-part) are the same.  There must be at  
least 1 non-dot character before the '@' part of the e-mail address.   
So the e-mail address provided is correctly identified as invalid.

FYI: this would be the correct way to represent that address:

"c.p.c."@something.com
