While Thunderbird developers are trying to emerge from a prolonged beta, based on them program other craftsmen make good programs, showing how to be really mail client. Postbox just an excellent example of software innovation and creativity.
The program has collected in itself all the features that users ask: here you and tabs, and working with RSS and news feeds, and tags, and a quick search, and it works very fast and looks - beautiful and compact. I would like to mention two feature display of quick filters on the content of messages and display of contact and other information about the letter (the message).
If the message contains pictures, attachments, links, everything is taken into account, and then quickly filtered and issued in its purest form. Here is the filtered image:
But links:
I enjoyed another feature: the program can advertise any message in social networks, bookmarking services and pictures.
Just from any message you can get the job done. In general, according to the settings - it is the most common Thunderbird, but the interface and finds opportunities - full Postbox.
Do not pass this program, it is worthy of attention: http://postbox-inc.com/.
