2.0B7 Mail conduit is not compatible

After installing Beta 7 the MailConduit is still incompatible. I thought, that was fixed?

Which version of Mac OS X are you using? 10.6 or 10.6.1?

I am using 10.6.1

I am having the same problem with SL 10.61.1. The Mail version is ‘Version 4.1 (1076)’

I’m on 10.6.1 and have the same issue.

Apple Mail does not permit third-party plugins at all so what we did is basically a hack. But, with 10.6.1 Apple broke this hack and we need to re-adjust. We will post an update as soon as we have figured out what Apple has changed recently.

Just reinstall the Mail plugin through the Help > Install Add-ons and it will work again. You may have to do this for every new version of Mail or Mac OS X 10.6.x.


I did this before, but that does not fix the problem.


I just downloaded the official disk image, removed my Mail plugin and ran the Install Add-ons procedure. Mail works fine with our plugin loaded.

I did the same procedure as you yesterday, and today installed your mail plugin three times again. It does not work for me.

Best regards,


Apple hasn’t made more than one version of 10.6.1 available as far as I can tell. I know my code is working for this particular problem, so something is not right on your machine. Please go to our downloads and download the disk image again and reinstall the application from that disk. Make sure to delete ~/Library/Mail/Bundles before starting DEVONthink Pro Office just to be sure that the new version is installed (you will have to quit Mail by hand for this to work).

Uh, I don’t think this is going to fly. I am having the same experience as Raed23.

The ~/Library/Mail/Bundles folder cannot be removed or an error is generated when attempting to install the plugin. I think actually you meant only that we should remove any contents relating to the prior installation of the DevonThink plugin before attempting to reinstall?

In any event I recreated the Bundles folder, made sure I had write permissions, then ran the plugin install. This created the appropriate plugin folder etc. inside the Bundles folder. I then ran Mail and got the following error message:

I then checked and the system had renamed the Bundles folder with the DevonThink plugin as “Bundles (Disabled)”, then created a new, empty Bundles folder. Of course when I opened Mail the plugin was not there in the menu.

If enough people have this problem it is for all intents and purposes something that should be dealt with.

I know Mail plugins for Snow Leopard are a hassle for other developers too - neither MailTags nor Letterbox are available yet in a stable version.

Very interesting! Yes, you should not delete Bundles, only the bundle in it, I guess.
After installing DTPro once more - the Bundles folder is empty, before and after - I can import my mails again into DTPro.

You reinstalled the entire app? Did you have to uninstall it first?

And if the Bundles folder is empty, then where is the plugin? If it isn’t there, what is doing the importing of the mails into DTPro?

Hello Usable_Thought!
Yes, that is the question. Seems the import from Mail without the conduit works very well.

Please could you verify that?

For the time being, it looks like the conduit does nothing, except it generates an error message :smiley: .


Reinstalling DT produces exactly the same problems as before.

For both of you: please send a message to support@devon-technologies.com with the following information:

  • What do you see in the Console (found in Applications > Utilities) when you start Mail?
  • How did you install the application: through the updater or as advised by downloading the application afresh from our website.

OK, so I’m not crazy - there is a real problem here. Apple caused it, but plug-in developers need to deal with it - see this article:


I’m very aware of that and I have a solution that fixes it when you reinstall the Mail plugin. But I have no idea why it doesn’t work for you. That’s why I would like the information I asked for through the support site so I can follow up with more specific requests if necessary.

Ah, I may have the answer - I was running Mail as a 32-bit app. Restoring it to 64-bit allows the DevonThink plugin to install OK.

For me this came about because the developer of LetterBox had released an early beta for Snow Leopard that worked, but only if you went to 32-bit for Mail. His latest beta now works with 64-bit also. His UUIDs are identical to those being used by the DT plugin.

The console error I had been getting for DT was this:

9/16/09 4:08:25 PM Mail[6953] SnowLeopard.mailbundle failed to load. The error was:
Error Domain=NSCocoaErrorDomain Code=3585 UserInfo=0x574580 “The bundle “DEVONthink Mail Import Support” couldn’t be loaded because it doesn’t contain a version for the current architecture.” (dlopen_preflight(/Users/frankslate/Library/Mail/Bundles/SnowLeopard.mailbundle/Contents/MacOS/DEVONMailConduit-SnowLeopard): no suitable image found. Did find:
/Users/frankslate/Library/Mail/Bundles/SnowLeopard.mailbundle/Contents/MacOS/DEVONMailConduit-SnowLeopard: mach-o, but wrong architecture)

At any rate it now installs fine.
