How to suppress the "sent from zoho.com" and "signed by zoho.com"

How to suppress the "sent from zoho.com" and "signed by zoho.com"

Hi,

I have been using gmail with a POP setup to access my email server at a domain hosting provider. Now I want to benig sending and receiving emails through zoho instead. I set up the POP account without a problem but find that the lines:

"Sent from zoho.com"
"Signed by zoho.com" 

turns up in the message info in every email I am sending. Is there any way I can suppress this information, which can be confusing for the receiving party?

Thanks in advance,

Anders
