Zoho IMAP - Sent mails folder issue

Zoho IMAP - Sent mails folder issue

Hello!

I am using Windows Live Mail on Windows 7 as mail client for ZOHO, cofigured on IMAP standard.
Everything works find, with a small exception. Each time I send an email from the client, that email is being saved twice in the Sent Items folder, on the server.
I assume that both the server and the client save on their own a copy of the sent email. But the problem is that Windows Live Mail has no option to disable saving sent emails.

Anybody can help me with this?

Thanks!
