Mozilla is a fully featured email program with flexible filters, good IMAP support, powerful searching, strong HTML and plain text support, really useful free-form tags and views for prioritizing and organizing mail, S/MIME encryption and — probably most importantly — many great features that help maintain computer security and personal privacy.
You can turn off JavaScript and remote images as well as cookies and still enjoy a comfortable email experience. That's also thanks to great spam filtering.
