[Dovecot] backup & restore mailbox files manually

[CoolAtt NNA]

When I delete the mail file from /Maildir/cur and restore it from the backup , I cannot see the body of the email when I 
view it (only the subject appears)

I restored only a single mail file using scp:
scp root at backup-host:/backup/vmail/coolatt/Maildir/cur/1264489757.P14232Q0M667471.ecs,S=628:2,S  /home/vmail/coolatt/Maildir/cur/

Please help me.

Thanks
CoolAtt
