Mole, thanks for the detailed post, I see some good tips there.
I just have two tips to share. First, I have selected the "read all messages in plain text" option in Outlook Express, this can reduce the chance of email virus infection and sending signals to spammers using HTML email. Also, spammers are more afraid of ISP admins and the like, so I often use a more scary

email alias like webmaster@, hostmaster@, admin@, etc.
