Given I have a tracker with global notification sent to a mailing list support@myawesomecompany.tld
And email gateway feature is activated
When a notification is sent following an artifact update
Then the notification contains an invalid token (user_id = 0 since support@myawesomecompany.tld is not a Tuleap user)

This is an issue since I, as a ML member, think that I can answer to the email whereas it won't work (and I won't receive any feedback).

MailGateway works only for individual emails.

I suggest that whenever a recipient does not correspond to a regular user, then we should send as no-reply instead of forge__artifacts, and not include the useless token.
