"Fixed" does indeed not hit the point, but do you have a better
suggestion?

The idea was to allow the system to used a fixed address, or a fixed
addressing scheme, no matter if the variable part is a RFC subadressing
detail or some other kind of subadressing, that can be recognised as such,
telling the mail "comes from the notification system".  The quoted part
tells exactly what was tried to express.  I would appreciate a better
wording, but can't think of any.

It is definitively a SHOULD, if we can't even specify it sharply.
