I have recently fond that I have the same issue : exporting to mbox as you
describe does not work properly. It creates an homongous file of several GB.

For instance : one of my local folders has 398 messages and the storage
space in .local/share/evolution/mail/local/.mylocalmail/cur takes 31MB
but the mbox file written when selecting all messages and saving as mbox
takes  6.7 GB !!!

I'm seeing people struggling with this since Ubuntu 10.10 !

Can nothing be done ? I was used to backup my e-mail every 6 months in an
mbox file (as was the native storage for previous versions of evolution) and
storing this on a file server. I was sort of a convenient 1 file for 1
period and 1 mailbox format. Now his has become impossible.

I started writing a small python program to collect the files in the 'cur'
directories until I noticed that these are not directly in mbox format as
well ... there is some extra information and the From line is not at the
beginning of the message.

I would be grateful for any help I can get on this.
