Letterbox

0.24b9
05 March 2011

Adds three-column view to Mail.app; does not support OS X 10.7 or later.

Overview

Letterbox is a plugin for Apple's Mail.app that takes advantage of your widescreen monitor. It rearranges the interface into three vertical columns so the message pane is to the right of the message list, rather than below.

What's new in Letterbox

Version 0.24b9:
  • This version of Letterbox is compatible with Mac OS X 10.6.7 and the build of Mail on new MacBook Pros.
  • Still incompatible with some Mail plugins that also use Sparkle for auto-updating.
  • The two-line combined From/Subject column doesn't play well with fonts other than Helvetica and Lucida Grande.
  • Changing the preview pane position with the menu item or keyboard shortcut does not visibly change the value in the preference pane.

This is a great app! sadly it doesn't work with Lion. The reason we need it for Lion is for the reasons Carina stated. While you can change the amount of lines that show in vertical pane preview its still too wide/high and you can see your mail easily. I like the thin line of the classic way but vertical which only can be accomplished by having letterbox run on Lion. I would keep it the classic version of Mail and use letterbox to make it vertical. Im hopeful there will be a fix soon. I can assure you there are many people that don't like the new vertical view. thank you - g

Dev's site has changed, it's now: http://montivagant.com/software/letterbox/ And it states clearly:"I do not have a version of Letterbox for OS X 10.7 and 10.8. These versions of OS X support a 3-column view in Mail." The Show/Hide function doesn't seem to work on 10.6 (though it does on 10.5), except for that, it's ok. ;-)

I have downloaded Letterbox for my wife's Macbook which runs OS 10.4. Having briefly enabled the Mail viewing pane to be to the right, it has now crashed Mail completely. Opening Mail brings up the top line menu but no Mail visible, so she has now lost everything. I have moved Letterbox to trash having attempted to uninstall 1st, with no effect. Help much appreciated.

did you get letterbox to work on Mountain Lion 10.8.2? I actually can get it to install and open in preferences using mailpluginfix, but it still doesn't work ??

Love this plug in!! Can't live without it!! The standard Mac view truly makes no sense. Wish every Mac user knew about this little gem.

You may try this: http://www.macupdate.com/app/mac/37804/mailpluginfix (and tell us if it works for Letterbox! ;-) Googling around, you might found a Terminal dealing with the file /System/Library/Frameworks/Message.framework/Resources/Info.plist to authorize mail plugins! (I haven't tested it neither) Good luck and let us know! :-)

What OS? I'm still on 10.6.8. I probably should have mentioned that.

How come this is not available for Lion / ML? I'd pay $50 for that plugin any day.

With Lion (and Mountain Lion) Apple has basically made it impossible to hack mail to this... only they have the keys to the kingdom... And, separately, I share your frustration. Apple's implementation is not ideal in either 10.7 or 10.8.

Now seems to be broken. Mail gives an incompatible plug-in error on launch and disables it.

Here's one more vote for a Lion / Mountain Lion version. For me, the new 3-column view in Mail is unsatisfactory - hard to read and not well integrated. For example, while I can increase font size in the Message List, this only works when Mail is set to Classic view. Letterbox was a near-perfect product for me in Snow Leopard, and I'll greatly appreciate an update moving forward.

I can't agree more. I am missing WideMail (great plug-in alternative to Letterbox) with Lion. The multi-field sorting in the 3-panel view is such a great way to handle emails.

Letterbox is a great little program. I agree with many of the postings here, that the Lion version of mail, while giving the 3 column view with one hand, has made the middle column useless. What a disappointment! Problems with the new middle view: - abandoning columns makes sorting by a column nearly useless. You can still sort, but it has no value as you cannot see the results of the sort. - not having nice columns makes the info harder to see - I am thinking that they decided to adopt the design used by many smart phones, without realizing that they are severely degrading usefulness - the often-mentioned lost of the bolding function, which no longer works except in classic view So as many others have said, the classic-plus-letterbox design is far more useable. Even with the difficulty Letterbox has always seemed to have in sizing the third pane (either too big or invisible in many cases, unless you resize the whole window to get it to behave). For this reason I am downgrading the stability rating. So I am another one who is eagerly awaiting the new Letterbox for Lion, as I don't expect they will want to fix it at Apple. But in case you are listening Apple: it would be really best if there was a "classic-middle" that kept the new features for the third column, but left the middle column in classic mode.
