I have dedicated 5GB of space for my home folder. I have 6 email boxes and when I add them to Thunderbird it downloads everything from them and fills up the whole home folder (3-4GB). This is unacceptable. I need to be able to limit its cache, I don't need all of the emails downloaded, just the new ones.
I tried setting lower space at
Edit -> Preferences -> Advanced -> Network & Disk space but it does not work, it again downloads 3-4GB of messages...
How do I limit it to 100-200MB?
