Yes, its an SMTP bounce, not a store, try to forward and return. I should have clarified. > Right.

Yes, unfortunately there are draw backs, I try to make the 550 bounce as informative as possible, (url link yadayada) but.. With a maillist I see the responses because I allow email from the network that serves the maillist server, in this case NANOG (: So... As needed I add IPs/Netblocks, but like I said very much over kill and administratively burdening. But the upside is (I think maybe 1) spam email in the last 3 months. I still get a count on the spam bounces, which have decreased, month 1=1752 bounces, 2=1292, 3=899. Again not an answer, more like a campaign.. Just my 2Âs on the whole thing.
