The ReplyTo field is set using the val_SetReplyTo operator. The SMTP server may require that the user be known to it in order for the message to be transmitted.
The email address you provide here should be a single email address, and should meet the requirements indicated under Email Address Syntax , (excepting that multiple addresses are not allowed). You must provide a valid sender email address for each email message.
