I apologize if you've gotten spam seemingly from my domain. Spambots remotely hijack others' computers using viruses and malware then use those computers to send spam on the spammer's behalf. These spambot program spoof spam as [if] coming from my domain. The spammers are angry that I report all spam to SpamCop.net which blacklists email hosts which relay spam, forcing spammers to daily adjust their viruses. The best thing we can all do is to have good computing habits to stop malware from infesting any computer.
