I am not sure if this is the right place to post this. However, I would like a feature - specifically I would like users to be able to join my site by using some characteristics of their email address. For example, suppose I want to allow all people who have an email address end in conagra.com join my site. I would like to be able to specify that domain and then if a user shows up they self register as long as they use that @conagra.com address.

So this would require an authentication email sent to their @conagra.com address that they then click and submit their username etc. Further, I would like it if they can only register with this particular email address for access to my private site.

The advantage of this is I don't have to manage memberships by hand - if I allow all users of a particular domain access then I don't have to do anything else other then manage the list of domains allowed access.

Further, I would like the ability to catch all of the bounces back when a message is sent to the members that automatically deletes from membership all returns because of 511 errors.

This would save me significant management headaches and I would be happy to pay for this as an additional premium on my regular service.

I want to note that I understand I can give potential users passwords but the problem is that passwords are either shareable or they have to be assigned one by one.

Thanks
