[Evolution] a question from newbie: how to restore messages, which were imported to Evolution and which were NOT left on server

[Tokufumi Kato]

Hi,

  I started to use Evolution and was able to set it up, so I was able to 
import my e-mails from my account. Unfortunately, I didn't set the option 
for message storage "Leave messages on server".... So, after importing all 
of my messages on the server, of course all were gone.
  My question is, is there any way to restore all of my messages back on 
the server?
  Thank you very much,

Fumi
