. Putting 2 and 2 together, I just had a great idea for you spammers out 
. there!! ASF uses The mail archive to archive their mailing lists and 
. make them publicly available via HTTP. The mail archive has one huge 
. fault though. It allows the option of responding to people who 
. originally posted directly without needing to login or anything. This 
. can give a crawler (with some interpretation) the email address of the 
. poster.
. 
. How do you set up mail archive to work? Get a mail archive account and 
. sign up that account with the mailing list you want to archive.
. 
. Suddenly, you have an instantly crawlable mailing list. Completely 
. vulnerable.
. 
. Just thought I would post that if anyone needed help in their spamming 
. exploits.
