Disposable addresses are great, but would be even better if I could associate a disposable address with a correspondent in my address book. For example if I have created a disposable address for use with emails to 'John Johnson', when sending him an email I have to search the drop down list for xxxxxx-jj@yahoo.com. If I had set that in the address book I would like the system to automatically use that preassigned disposable address. This would be a nice enhancement to Yahoo Mail Pro!
