After receiving an email bounce, I realized that an inactive member on my site had been watching a very active forum.

He was getting emails every time a new topic was created.

He hasn't been on my site in probably two years.

I became him and changed his setting.

However, I wonder if there is a better way to deal with such scenarios to eliminate unnecessary emails from being sent.

Maybe an expiration on watch lists?

Any thoughts?

would be a great idea to have such a thing.

I'd like to have the option to have a dedicated email for the forum to handle any bounce or response to a PM. I get a ton of random emails from my forum and it is tiring to have to go in and manually set people's setting to not receive emails on PMs. I'd love to see where if their email bounces it would make them revise their registration with a new email. If they respond to a PM it could add that response to the actual PM.
