I would like to have an email client which reminds me about an email, that I sent say a week ago, but to which I have not got a response yet.
My question is similar to this one, but the difference is that I do not need a web-service and I would like to have some open-source application locally installed on my machine (like Thunderbird or Evolution).
I also try to avoid using big email services like GMail.
I have already checked among the Thunderbird plugins, but have not found anything.
So, the question is: What software/plugin can help me to follow up my sent emails which do not have responses?
