This From contains 2 mailboxes (Lastname and [email protected]). This is
valid RFC 5322 syntax
from = "From:" mailbox-list CRLF
...
mailbox-list = (mailbox *("," mailbox)) / obs-mbox-list
but it's invalid for DMARC RFC 7489 and it's not covered by DMARC
specification:
The absence of a single, properly formed RFC5322
<https://tools.ietf.org/html/rfc5322>.From field renders
the message invalid. Handling of such a message is outside of the
scope of this specification.
Processing of message like this is implementation specific, any
implementation does not violate RFC 7489.
