Forum OpenACS Q&A: Response to Encoded Email for Webpages
I used to get ~1000 spams a month, and since I was checking my e-mail, perhaps only once a month, in i-cafes, in Mexico (with speeds varying from 9600-54000 bps), pop3 transfer times were significant and costly.
I have since installed spamassassin. It seems to work well, scoring spams based on regexp patterns. I have the option of adjusting the threshhold level. So far, I toss anything that scores over 14 to /dev/null, and anything greater than 5 goes into my grey bucket. I still get spam, but less than 1 per day.
I guess my point of all this is that I found that with spamassassin. rewriting web pages to protect spam harvesters proved unneccessary.
