true, it's illegal to have an '@' in a phrase unless its quoted.
it was illegal in RFC 822 also, which means it's been illegal for 20
years or so.  an '@' can't appear in an atom.

perhaps even worse, it's redundant.  why say 

user@domain.com <user@domain.com>

or even

"user@domain.com" <user@domain.com>

when simply

user@domain.com 

will do?  

a phrase containing another copy of the address conveys no additional 
information, it just wastes bandwidth and invites stupid mail handling tools
to play with it.
