PETERNSTEINMETZ  Looks very nice in terms of UI and indexing. There are some details missing that prevent me from adopting at this time.

Does not appear to use the system keychain. So if you have a server with a certificate signed by a local certificate authority, whose certificate is loaded into the system keychain, PostBox will not validate it.

Has troubles using an SMTP server with smtp over SSL using an unsigned certificate (or one such as above). It does not prompt to accept such a certificate for the smtp server (though does prompt on the imap side).

Doesn't appear to recognize mailboxes on the imap server properly. You can fake it by creating a folder on the server in Postbox, then swapping the file on the server, but that is an ugly hack. Postbox appears to just not be checking right now for existing folders on the imap side.

No support from/for SpamSieve yet.

Overall, this seems like a mid-beta product and would more appropriately be priced that way.

There are a lot of details about the server interaction to get right and really offer a full service mail client. Some of these not done yet in PostBox.

I personally could live with all of these, for the sake of development of a nice new client such as this, but not the issue with the SMTP server. On a laptop moving around, I just want to be able to always use my own SMTP server running on a strange high numbered port and want it protected by SSL.

SHOOFLYSHOO  Stellar piece of software. Looking forward to further updates. Only thing I wish it had was the ability to see all the mailboxes in one global inbox.  
(Version 1.1.2)

22DUKE  yes has potential but not there yet

Still has annoying bug where it opens messages in new tab even though you did single click

no proper HTMl

no templates

no possibility to insert hyperlinks

no easy way to colour read or unread messaged differently  
(Version 1.1.2)

LEONLEDRAGON  I dont see any possibility to use templates - to use groups - to use services

Some mails are presented in html code !

Maybe there are some tricks to make it working for me ?

B. JEFFERSON LE BLANC  Postbox definitely has potential. But I recently updated to Eudora 8.0b9 and the Penelope component is finally compatible and stable with Thunderbird 3. The spam filter is finally working as well, which has enabled me to migrate from Thunderbird 2 and SpamSieve, which Thunderbird 3 does not support.

Among other things, Thunderbird/Eudora can be searched by Spotlight, and it has a unified in box, features people are still waiting for in Postbox. Oh, and it's free. Which means you can use it at no cost until Postbox matures.

FUHAYER  does this new version include global inbox for more than one accounts or not yet ? i am just waiting for this feature to buy and use.

ROBERTCOOGAN2  Very nice app - the last Thunderbird releases (v3.X) were buggy, plus Apple Mail's issues with Gmail left me searching for a replacement. Postbox fits the bill perfectly. No crashes, and it sets itself up in seconds.

My only complaint: There needs to be a consolidated Inbox. Right now I can only look at my Gmail and MobileMe e-mail accounts separately, it would be nice if they both appeared in a single Inbox.  
(Version 1.1.1)

JAGOOAH  I bought Postbox at version 1.0 to support the developers, but was initially very disappointed. The integration with OS X was nearly non existent. I stopped using it within days - especially as I use Spotlight constantly and Postbox emails did not show up: every time I searched for an email and clicked on the result, Apple Mail would launch. Very annoying.

This lasted up until 1.1.0. But with 1.1.1 EVERYTHING has changed for me. Integration with OS X is now very good - and I am sure it will improve even more over time. The combination of all the features of Postbox + the OS X integration makes it a killer product. Frankly, version 1.1.1 is misnamed: it should be at least version 1.5, if not version 2.0!

Well done Postbox developers for such an amazing upgrade - I am sure many long work hours went into it. Now, I hope you will concentrate on the eye candy a bit more: the interface still smacks of a Windows XP crossover.

To all power email users out there: give Postbox a try. It is leagues better than Thunderbird and Apple Mail.

DEJA VUE  I used Trial version of the most recent PostBox 1.1.0.

I specified Gmail only - it was the only account!

I checked "Leave messages on server"!

After a while I wasn't satisfied with the product and I deleted (with AppZapper) entire product (Inbox with some 50 emails). I was thinking my emails will stay intact on Gmail server as they stay when I use Entourage or Mailplane!

It was not the case.

Can you imagine - all 50 messages gone "with the PostBox"!

Well, I will not recommend this app to any of my friends. And I will not purchase it ever.

Thank you.

22DUKE  I actually have to revise my previous review. Now after several weeks of working with the application on two different machines I switched back to mail.

The gmail/IMAP implementation is just not working, email's arrive delayed, statuses are not updated, messages cant be saved errors on a frequent base, very, very slow to send email in comparison to mail and the application does crash ever so often.

Promising app but not worth the money at this stage.
