A combined email database, news reader, mailing list organizer and RSS news feed reader, supporting both POP3 and IMAP protocols.
Pros & Cons:
Opera Mail (previously known as M2 Mail Client) is another option that many people are not aware of. It comes from the same source as Opera browser.
Although there is no calendar in this program as in Outlook (it wasn't meant to compete with Outlook anyway), it is still quite powerful. This email client is a combined email database, news reader, mailing list organizer and RSS news feed reader, and it supports both POP3 and IMAP protocols.
My experience with it was quite pleasant. It was easy to set up, very intuitive to use, and it easily found any contact I had ever had email correspondence with. Overall, it's a very nice product.
That said, Opera Mail is now at the end-of-life stage of its product life cycle and it does not provide further updates and technical support although the product is still available to download from the developer's site.
