Store incoming emails?

Is there a software that will allow me to store incoming emails in a list or some form of basic CRM system?

Well I know of a few applications which would work in conjunction with Outlook it that's any use. OpusFlow CRM for Outlook for example although I've never used it, so can't say if it's any good.

sorry missed some important details. I need to be able to access these emails from any location.

I though Interspire Email Marketer could do this but apparently not, according to their support team.

There must be some simple software that can do this.
