Let me break it down for you one more time:

,-<https://tools.ietf.org/html/rfc5536#section-3.1.2>
| 
| 3.1.2.  From
| 
|    The From header field is the same as that specified in Section 3.6.2
|    of [RFC5322], with the added restrictions detailed above in
|    Section 2.2.
| 
|    from            =  "From:" SP mailbox-list CRLF
| […]

,-<https://tools.ietf.org/html/rfc5322#section-3.6.2>
| 
| 3.4.  Address Specification
| 
|    Addresses occur in several message header fields to indicate senders
|    and recipients of messages.  An address may either be an individual
|    mailbox, or a group of mailboxes.
| 
|    address         =   mailbox / group
| 
|    mailbox         =   name-addr / addr-spec
| 
|    name-addr       =   [display-name] angle-addr
| 
|    angle-addr      =   [CFWS] "<" addr-spec ">" [CFWS] /
|                        obs-angle-addr
|    […]
|    display-name    =   phrase
| 
|    mailbox-list    =   (mailbox *("," mailbox)) / obs-mbox-list
| […]
| 
|    A mailbox receives mail. […]
| 
| 3.6.2.  Originator Fields
| 
|    The originator fields of a message consist of the from field, the
|    sender field (when applicable), and optionally the reply-to field.
|    The from field consists of the field name "From" and a comma-
|    separated list of one or more mailbox specifications. […]
| 
|    from            =   "From:" mailbox-list CRLF
| 
|    […]
| 
|    The originator fields indicate the mailbox(es) of the source of the
|    message.  The "From:" field specifies the author(s) of the message,
|    that is, the mailbox(es) of the person(s) or system(s) responsible
|    for the writing of the message. […]
| 
|    In all cases, the "From:" field SHOULD NOT contain any mailbox that
|    does not belong to the author(s) of the message. […]

But:

| $ host -t MX inter.nl.net
| inter.nl.net mail is handled by 20 mx20.se.isp-net.nl.
| inter.nl.net mail is handled by 10 mx10.se.isp-net.nl.
|

`----

(The same is true for mx10.se.isp-net.nl.)

IOW, exxjxw.hannivoort@inter.nl.net is not an e-mail address.

> As for Netiquette, the rules obviously depend on his nationality.

Of course not.
