spam blocking

We started using the Spamhaus Block List at about 9am on Wednesday. To date, okcomputer has blocked 192 messages thanks to the SBL.

We also started processing all mail with Spamassassin. According to evan's calculations, Spamassassin has tagged over 900 messages as spam so far. I set up my mail client to filter based on Spamassassin's report and got one false positve out of 5 filtered messages so far. That one was a user forwarding a spam to me with a question. Thankfully, I don't get a lot of spam in the first place.

I also put up the antiflux spam page. If you have suggestions or good procmail recipes for blocking Outlook viruses, let me know.

I get a lot of "Undelivered Mail Returned to Sender" for which I sent no mail. They are all 52k.

Is there anything that can be done?

Am I the only one who feels this way?

Chances are it's some Outlook virus on someone else's computer forging your email address as the source and sending to a bunch of random addresses, many of which don't exist. You could always use procmail to filter them based on some common string in the header or message body.
