How about the good old Mozilla Thunderbird? It's open-source, cross-platform and a lot of support is available online.

It covers all the features you need (except the optional one). Plus it has got full POP3/IMAP support and works well with all kinds of accounts. Here are some of the features I like:


Tabbed E-mail
Add-ons
Feature Requests
High Customizability
Awesome Search
Multiple Channel Chats


I've been using Thunderbird ever since I started using Linux (it comes integrated with Ubuntu). I haven't faced any issue so far.
