RFC 2822 does not allow this, as I read the syntax (omitting the
obsolete bits):
mailbox-list = (mailbox *("," mailbox))
from = "From:" mailbox-list CRLF
In other words, there's got to be at least one mailbox, and there's no
group-name as permitted in To: (and Cc):
to = "To:" address-list CRLF
address-list = (address *("," address))
address = mailbox / group
group = display-name ":" [mailbox-list / CFWS] ";"
[CFWS]
