Cant unsubscribe a user

Hi,

the unsubscribe link in the email doesnt work.

I’ve always done it by hand just changing the value of field in the wp_comments table, which does not appear to be there anymore.

How can I unsubscribe a user that wishes not to receive notifications from a post anymore?

Thanks in advance
