Mutt not following RFC821 strictly?

[Magnus Bodin]

As of RFC 821 <http://rfc821.x42.com/> the local part of an e-mail address
can consist of other characters than a-z0-9 and should then be quoted (see
local-part and quoted-string).

It seems though, that the mutt client does not support the use of an address
like "address with spaces"@x42.com which indeed is a valid and working
e-mail address. Or is there some way to enter addresses explicitly thus not
having it "parse-mangled".. 

Can anybody confirm this, without having me to poke in the source. 

If so, isn't this one of the standards that shouldn't be broken?
