Postbox 3.0.10 adds Retina support on OS X, auto-resizes images

28 May 2014, Nick Peers

PostboxPostbox, Inc has updated its cross-platform, commercial email client with a minor update. Postbox 3.0.10 comes with added support for Retina displays in OS X.

The new release also now automatically resizes images to fit in the message pane window for readibility purposes, plus allows users to whitelist an entire domain for loading remote images.

The undoubted highlight in version 3.0.10 is Retina support. Postbox has revealed its spent months redrawing hundreds of icons for both colour and monochrome themes in order to make the icons Retina-ready. This was accompanied by other necessary layout changes.


Postbox continues to evolve new features with this new release, and is now Retina-friendly on Mac.

The new image-resizing feature is designed for user comfort. Previously after inserting an image into the body of an email, pictures would be displayed at the size they would be sent. Now the image automatically rescales according to the size of the message pane window.

The final new feature involves remote image whitelisting for domains, making it easier for users to insert remotely hosted images from safe websites into their email messages. When the Load Images button appears, users are instructed to click the pulldown menu and select the sender domain, which whitelists it going forward.

Version 3.0.10 has also seen its French, German and Italian translations improved, while the migration assistant’s wording has been tweaked to make it easier to follow. The existing Lightning add-on has also been updated to work with Mac Retina displays.

Notable bug fixes include resolving a slowdown issue with Yahoo!’s IMAP servers as well as fixing a bug that prevented certain preferences from being saved. Finally, Address Book notes should no longer overflow.

Postbox 3.0.10 is available now as a 30-day trial for Mac (OS X 10.6 or later) and Windows (XP or later). The full version can be purchased for $9.95 plus applicable taxes.
