Personally, I would locally blacklist each such rude far-end, giving the sender an immediate error return at smtp-time, send an explanatory note, then wash my hands of such damn-foolishness. ISTR that it is possible to greylist more intelligently, (if one must at all), so as to not give you that specific sort of grief in a frequent different-message, same source, environment. But I am a notoriously 'unhelpful' old curmudgeon, so something gentler may be in order.... YMMV, ;-) Bill -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
