[twincling] export mails from kmail

[y2k_sonu]

Hi ,

I am a Suse 10.1 User with kde.
I use kmail as email client.
I want to take backups of my emails i have.
I didn't found any export/Backup utility in kmail.
If kmail doesn't have any export options then how can we backup our mails?

Thanks
Sumit
