and probably ```temporary``` could go to, since from these examples at least it is reported only whenever it is some local failure... or may be it would be there also during graylisting, but we should not ban those either I guess by default... yeap:

We could add a new filter exim4-greylisting or exim4-spam where we would add this specific one, so greylisting becomes even more effective, but I do not think we should be messing with default jail for this.  What if someone sets bantime to a day or so? ;)  We would already be stretching with "local_scan(): Rejected" since the same server might provide spam and non-spam emails and we probably do not want to ban a whole server (e.g. gmail?) because there is few spam messages getting through it.
