Change placement of sent messages

In Thunderbird I have the option to say that sent items go to a certain folder (in my case I want it all in the Inbox) and that replies go to the same folder as the original message to which I reply.
Are there corresponding options in emClient?

No, it is not possible at the moment. You can create a rule moving all sent items to a folder, but it is impossible to move replies as you described.

Then I’ll state this as a feature request. It’s an elementary functionality to keep conversations/threats together. So, when you are going to implement those, think about this detail. It’s a very neat functionality in Thunderbird.

It is planned to be implemented in the version 5.5.
