I don’t know if this will work for you, but check out this thread on Thunderbird, a free email client:
Is Thunderbird (email app) still good? - Factual Questions - Straight Dope Message Board
I was using MS Office Outlook for years until some security changes made by my email ISP made it stop working. I had some complaints about Thunderbird at first (and I would still prefer Office Outlook) but after making some configuration changes (described in that thread) I’m OK with it now. It looks like the security stuff may have been rolled back so I may be able to use Office Outlook again, but I’m not sure if it’s even worth going back at this point. But I have to have an email client – I hate the idea of being at the mercy of some email provider’s horrible web interface, and it doesn’t allow you to integrate different email services in one interface.
