Postbox has launched a new self-named, Mozilla-based e-mail application. The software features fast searches using operators, and a text preview mode. Content tabs allow quicker access to attachments, images, links and contacts. A related option is Find by Contact, which brings up messages, images, links and attachments for a specific contact in tabbed form. Messages in tabs can be ordered and reordered.

Topic organization allows grouping disparate materials for a project- or idea-based workflow. The app also features mail archival, to-do tagging and support for add-ons. Security features include anti-phishing and malware protection, and auto-updating to keep the program current.

Postbox works with Mac OS X 10.4 or higher and is Snow Leopard-ready. It costs $40, with an additional $20 charge for a family five-pack, and a $25 charge for lifetime upgrades.
