Opera 9.6 - Follow and Ignore Threads, Email with Little Bandwidth

Opera, the bel-canto browser that also plays excellent email, now can ignore threads for you — or track them for easy access under Followed Threads.
Also new in Opera 9.6 email is a low bandwidth mode that doesn't download attachments and only syncs new mail for IMAP accounts; for POP accounts, that mode just fetches 100 messages. RSS news feeds are now rendered beautifully in preview before you subscribe.
›› The Opera email client is a slick and flexible interface that will satisfy almost all your email needs, and Opera integrates RSS feeds in this experience as well. (Windows)
