imap: can I turn off zoho's sent folder?

Hi All,

When zoho copies my messages to its sent folder it removes my Bcc's.  I can have Thunderbird handle the sent folder on its own without any help from zoho's server and Thunderbird will retain my Bcc recipients.  Can I turn off zoho's copy to sent folder so I don't get two copies if I turn my Thunderbird sent echo back on?

Many thanks.
