I'm at my wits' end here and not sure what to do.... Have an Exchange 2000 install w/ SP3 and security rollup installed. I believe relay is configured per MS instructions. What's happening is the badmail directory is filling up w/ a few thousand entries everyday. It appears that someone is sending spam to every name in the dictionary attached to @mycompany.com. When I look in the ESM, it shows a couple dozen queues in the SMTP Protocol from domains that are basically "junk." Tried putting these to be filtered out, but they keep coming back w/ other domain names. Is there anyway of keeping this stuff out or is it something I need to live w/ since this users are not getting this mail. Thanks. Lee Ann Lake Norden, SD
