not just random

One growing trend in the connected world appears to be email bankruptcy. Go ahead, google it. Not good. But: There clearly are needs, maybe opportunities.

Rather than solving the problem or contributing anything real useful, I am presenting a brief list of things, I want in email software:

• Indicate the length of new text in an email, excluding quoted text from previous messages in the same thread.
• Indicate, if a message contains one or more questions.
• Prevent retrieval of additional emails, if there are still unprocessed old ones.
• Allow specifying if I am waiting for a response in a given thread.
• Customizable reminders if an expected response has been overdue.
• Various whitelists.
• Syndication feed reader.
• Assigning feed items as well as emails tags/values indicating their importance or probable interestingness.
• Smart templates and auto-responders.

An incomplete wish list, mostly. I really am looking for a good, customizable email client though. Something smart.
