I'm running Thunderbird 24 on Ubuntu 12.04 64 bits. I have installed the Conversations extension, in order to group and visualize conversations based on threads, in a similar way to what gmail does.
It works fine, but it seems to depend on Thunderbird's internal native thread grouping mechanism, that is itself a bit flawed. In the example below, this thread include four different subjects.
I know many will say the threads are grouped based on an internal flag and if a contact of mine lazily uses a previous message, click reply to obtain the address list of an existing message and use it as a basis to compose a new message, with a different subject, then the new message will be automatically threaded as a child of the original message.
The problem is:
- I can't educate ALL my contacts. Simply impossible;
- Thunderbird is grouping messages with different subject lines
- I have received automatic messages from external services, (meaning it's impossible they had hit "reply" on a previous conversation) and even then it gets grouped on a wrong thread.
Is there a way for me to improve the way Thunderbird will group threads? Or alternativaly a way that I can manually exclude and include messages from threads (that doesn't involve having to manually edit headers)?
