I like this.

I don't think you need the password here. Mailback validation is 
fine, because it proves ownership (or at least access to) the email 
address. If you're being attacked, and they can read your e-mail, 
being subscribed to a mail list is the LEAST of your problems. No 
sense making the mail list service more secure than your e-mail

yup. That's on my list somewhere, too.

for subcribes and the like, that's generally what you want (but have 
the option of turning it off). The only place I wouldn't want it is 
unsubs. Make that as trivially easy as you possibly can, because 
there's no need to make it secure. Unsub attacks are basically 
non-existant, especially compared to the struggles of the 
naive-i-want-off-i-dont-care user.

You seem a decent fellow. I hate to die.
