My Email client of choice. Apple's Mail App seems too frivolous compared to this. Glad that this product supports the MBOX format, and doesn't force Outlook's PST crap on you. Importing from Thunderbird was a breeze. Has a fair bunch of great features, consumes memory but not too much. I'm kinda sad MSFT will kill this off in Favor of Outook in the next release. I'm afraid I'll go scurrying back to Mail.app when that happens. - Saket Vaidya
