I’m happy to announce Letter Opener Version 3 for Mac OS X 10.6 Snow Leopard.

Snow Leopard required a complete rewrite of Letter Opener. A big thx here to Scott Morrison of Indev Software for figuring out how to get Mail Plug-ins working in 64-bit mode!

The upgrade is free for everybody who bought Letter Opener after June 8, 2009. For all other users an upgrade is available.

You can download the upgrade from here.

Just to get your product mentioned in Macworld is a great bless, but to get a five star rating is a real tribute. Deborah Shadovitz did the review, here’s a quote from it:

With Letter Opener in Apple Mail, the worry is gone. Letter Opener converts winmail.dat files on the fly, so you can actually see and use what the sender intended you to have. There’s no fuss with Letter Opener, no need to drag the winmail.dat file onto another application or call upon several programs to help you. Once Letter Opener is installed, you can forget about it.

The pricing is always a tricky thing, so I was especially happy to read this:

If you regularly receive winmail.dat files from business associates, Letter Opener is well worth the investment.

In part one I describe how to set up an Exception Handler, Uli discovered as first one that this handles not all cases. The missing part is a signal handler to get information of SIGSEGV, SIGBUS, … signals.

I thought the hard part of this is getting the backtrace inside a signal handler. I already found code for this, but I couldn’t use it because it was GPL. I tried the easy way, offering the author money to release it under public domain, oh boy this was a waste of time. But now that I found my own solution for this I’m happy that I didn’t spend money on this. (1 line versus 20 lines of code)

I’m getting ready to send my iPhone Application to the first beta testers and so I started thinking about crash reports.

On the Mac you have two options to get the crash report of your application. The first one is to check on startup if there is a new crash report file in ~/Library/Logs/CrashReporter for your application and simply send it. (Example: HDCrashReporter , UKCrashReporter)

Beta 6 support winmail.dat files in encrypted messages, improved winmail.dat file recognition, and as always bug fixes.

Note: The last two betas include sparkle 1.5b4 and there are still some problems with that.

If you already using the beta, please use the build-in update function (Mail Menu -> OMiC -> Check for updates…), else just write me a line.

By the way, I’m try to get into this twitter thing, so if you like you can follow me.

This beta version fine tune the new integration into Mail. Also the winmail.dat converter itself got lot of bug fixes.

It took again a long time to release this beta, one of the main show stopper is the still existing GMail IMAP issue.

If you already using the beta, please use the build-in update function (Mail Menu -> OMiC -> Check for updates…), else just write me a line.

If you are using googles popular mail services GMail over IMAP and demand on winmail.dat files you will run into a problem.

GMail IMAP doesn’t return the senders original winmail.dat file, it return a home-cooked file which have only the name in common. In this case, not even Microsoft Outlook can handle the winmail.dat file.

I tried to contact google about this issue over many different ways, but didn’t get a answer.

There are two workarounds: Switch back to GMail POP3 or use GMail web interface to access mails with winmail.dat attachment.
