IDEA: email follow-up reminder

[urlwolf]

I'd like to have an application/plugin that does the following:

(1) it gets a list of contacts
(2) let's me assign a time deadline (e.g. a month) to them
(3) monitors when I last mailed that person, and starts counting
(4) when the deadline arrives, it notifies me

Is there any program out there that can be configured to do this?
Ideally, the program used to mail should be capable of implementing this kind of reminder. I use Opera M2... so no plugin capability.

This may require then an external program that monitors email. Some are discussed here:

This idea is useful for those people that you want to keep in touch, but for some reason you keep forgetting to mail them...

Your idea sounds useful indeed, but I think that's virtually impossible, given the fact that many use different clients - and then there's webmail (yes, I love Google Mail).

Maybe it's better to use some kind of reminder tool? With web-based tools it's even possible to remind you if you aren't at your PC.
