Spike in rejected mail

Since 1am my inbox has filled with "user unknown" mail reject messages. I assume folks with @alcf addresses used to have / are subscribed to mailing lists with @mcs addresses. I didn't see any tickets regarding this --- yet. If we can roll that change back until we get the mailing list subscriber situation handled that would be good. ---- Daniel Murphy-Olson Systems Administrator Mathematics & Computer Science Division Argonne National Laboratory 630-252-0055
