> could update the trust level once all keylistings are internally done but changing the trust level while you are viewing a mail also seems kind of ugly.

Just an idea:
It would be okay, if the initially shown trust level would indicate that it is a trustlevel forcast
and some operation is going on in the background. Experienced users could come back later or wait.

Thks for your explanation Andre. We can wait for a major rev.

Another curious behaviour is that the blue stamp icon on the left in msgs list can appears or not for the same type and sender of msg (trust level 4).

Hi,

I don't really have a fix for that. But maybe it helps you to understand the reason behind this:

For trust level 4 GpgOL checks if one of your own keys, or keys that you ultimately trust, has directly certified the key of the signer. For that it needs to list all your keys and build up it's own keycache, so it's own understanding of how your keyring looks like, then it has to check all the signatures of the signers key and check if there was a valid signature made by one of your keys. As this can take a while this is all done in the background. If this is not done yet when you view a mail it will only show what the crypto backend says "This key is fully trusted" that is the information that the crypto backend gives. That is trust level 3.

Doing its own additional checks will "later" raise that to trust level 4.
I'm talking with our backend developers about that and for the next major version of GnuPG we will have a "keyring deamon", which will be a long running process that has the information about all your keys in memory. That will greatly increase the performance of such operations and will allow GpgOL to quickly query the information it needs. So this problem should be resolved by that, or at least I should have the tools I need to resolve this issue.

I could update the trust level once all keylistings are internally done but changing the trust level while you are viewing a mail also seems kind of ugly.

Hope this helps to understand the problem.

Best Regards,
Andre

Curious behaviour: When I receive an e-mail from Microsoft it is classified as trust level 3. When i change to view another msg and come back it is classified as a trust level 4 (I trust this cert). Then is always shown as trust level 4. If I shutdown Outlook and restart it repeats this behaviour. Outlook 2013 64 bit.
