Hi, I am using SMTP for sending mails in my ASP.Net code. I have specified "Reply to" option in my code which is supposed to receive a mail to "Reply to" id instead of "Mail From" if any reply is sent to "Mail From" address. But when i send a mail through the ASP .Net coding to a email id which is out of office, the out of office mail comes to "Mail From" address instead of "Reply to". Please suggest do i need to change any settings in the SMTP/Exchange Server or i need to do extra code for the same. Thanks
