Add or document X-Microsoft-Antispam-Mailbox-Delivery and others

[RalphCorderoy]

Please consider decoding an interpreting other Microsoft header fields, for example:

• X-Microsoft-Antispam-Mailbox-Delivery
• X-Microsoft-Antispam-Message-Info

And if they can't be added for some reason, document in the README why not so future visitors looking to interpret them know they're not covered. Thanks.

This would be great! However there seems to be a lack of documentation, see also: https://github.com/MicrosoftDocs/microsoft-365-docs/issues/1682 and https://github.com/MicrosoftDocs/microsoft-365-docs/issues/7857.

If you see below in the email header with SCL 1 and SFV: NSPM then please do check the following attribute 'TrustedListsOnly' in 'Get-MailboxJunkEmailConfiguration'.

X-Microsoft-Antispam-Mailbox-Delivery: ucf:0;jmr:0;ex:1;auth:0;dest:J;OFR:SpamFilterAuthJ;ENG:(910001)(944506478)(944626604)(920097)(890001)(250001)(435001)(930097)(3100021);RF:JunkEmail;

If this is set to True then "Only messages from email address or domain entries in the Safe Senders list and the Safe Recipients list are delivered to the Inbox. All other messages are automatically delivered to the Junk Email folder".

Default value should be 'False'. You can use 'Set-MailboxJunkEmailConfiguration -TrustedListsOnly $false'.
