> Hi, Regarding my lost subscriber in Mauritius, thanks for several people's suggestions -- she sent Thanks and Info commands as instructed, and got back nothing, no response from either Thanks or Info.

If they get both responses, then all is well (for direct > addressed mail) and the spam filter is perhaps blocking BSMTP mail. I heard that some large companies briefly shut down to deal with the new ExploreZip virus -- Could something like this be going on? Mauritius probably is smaller than General Electric...... Meanwhile I signed her up with a Hotmail address, but would like to see what's going on with her primary address, so what's the next step? Thanks, E Perkins
