Because it matters to RFC821/2821 and RFC822/2822?

A space between words means something quite different to a 'space in a
quoted string'.

From: abc def <abc-def@someplace.com>
or
From: abc def <abc def@someplace.com>

vs.

From: "abc def" <abc-def@someplace.com>
or
From: "abc def" <"abc def"@someplce.com>

The "From: System Message" will be delivered to what address?
system@message, or system@localdomain.com and message@localdomain.com?

If you're not using the "X-Sender:" and "X-Receiver:" headers to
specify the sender and recipient addresses then the "From", "To", or
"Sender" headers must contain properly fromed smtp addresses.
