Postbox email client

Postbox was created by former Mozilla employees (engineering and product management) with previous experience in Thunderbird so you may find some similarities between postbox and thunderbird 3 beta.

Tab email browsing

Great feature! I've used it a couple of times to compare side by side two inbox folders. I couldn't find a way to have the compose email in a tab though.

Conversation views

Postbox will join together emails that seem to be related. It seems that it uses the subject title so it is not that precise. When i tried it , it grouped together two non-related emails because they had the same subject. It should compare not only the subject but it's headers. This is smth that Zimbra and thunderbird lacks too though.

Search

Search is intuitive, very good results and with lots of options. To test, i tried the same search params across different email clients and postbox returned the most accurate results.

Thunderbird plugin compatibility

This is awesome! You can use any thunderbird plugin in postbox. Even lightbox for your calendaring!

Interface/Layout

I found the layout to be similar to thunderbird but nicer and more stylished.

Thunderbird/Outlook import

First time i launched postbox it asked me to import from outlook/thunderbird which i did. My surprise was that it not only imported my account details correctly but it also imported my html signature and other preferences. Neat!

Imap IDLE

I'm a computer nerd and want to be notified of new email as soon as it arrives to my server so Imap IDLE is a must. Postbox supports it and it's connection pool is handled very well.

Cost

This is the only downside in Postbox. If you buy the "beta" pre-release version it will cost you $usd 30 and you elegible for an upgrade to the final version. A 33% discount.
