Has it ever happened to you that you sent an email, and right after, you wanted it back?
It occurred to me more than once. Either that I found some spelling errors, or just feeling like rephrasing a paragraph, or whatever.
The question is why not let the sender pull back a message in case the recipient had never read it.
Even if it would be hard to modify the SMTP and POP protocols it can be still done with in the same server/domain, e.g. gmail.com.
I think this feature is a good one. What do you think?
I really wouldn't want my email service to delay my emails when I actually click `send` - I sometimes rely on them being sent immediately.
