Sent messages appear twice, duplicate

Sent messages appear twice, duplicate

Hi,

I final got my zoho mail hosting working for my domain benporter.co.uk

Now I am sending and receiving mail okay. However in my sent messages the email is duplicated (this does not happen on the recipients inbox). This happens on any device/method I access the emails.

This is not a major problem but is curious and frustration.

Any help would be appreciated,
Thanks
