When using mutt I don't want all the messages to be cached, which could take up a lot of disk space. But if I purge an email, it also gets deleted on the server side, which is undesired because I may need to reference it in future. Is it possible to automatically clean up cached old messages when it's >100MB, while keeping those messages as they are on server and never retrieve them back to my laptop?
Can mutt delete message locally but retain it on server?
