Error in script when sending emails

Error in script when sending emails

Hi

my script has always worked but now I was trying to modify it and I could not save the new script. I got this error message: 

In cases where From: address is not a zoho.adminuserid or zoho.loginuserid, the To: address can only be zoho.adminuserid and the sendmail task cannot have any CC: or BCC: address.

The script sends an email from the address of a specific Zoho user ( USER@rossatogroup.com) according to the selected county ("Provincia") in the form. Each county ("Provincia") is associated to a Zoho user who is responsible for that area.

For example 

if((((((input.Provincia.contains("Chieti")  ||  input.Provincia.contains("Perugia"))  ||  input.Provincia.contains("Terni"))  ||  input.Provincia.contains("L Aquila"))  ||  input.Provincia.contains("Teramo"))  ||  input.Provincia.contains("Forlì Cesena"))  ||  input.Provincia.contains(("Rimini"))) 
{
sendmail
[
to:input.Email
subject:"Preventivo impianto a pavimento ribassato da Rossato Group"
message:(((((((("MESSAGE………..}

OR

if(((((((|  input.Provincia.contains("Pescara"))  ||  input.Provincia.contains("Ancona"))  ||  input.Provincia.contains("Ascoli Piceno"))  ||  input.Provincia.contains("Fermo"))  ||  input.Provincia.contains("Macerata"))  ||  input.Provincia.contains("Pesaro Urbino"))
{
sendmail
[
to:input.Email
subject:"Preventivo impianto a pavimento ribassato da Rossato Group"
message:(((((((("MESSAGE………..}


It doesn't work anymore.
Can you please check and let me know how I can send the email from the email address of my salesman and not from a generic email address?

Thank you in advance for your help.
