When I create the mail message, I am doing this:

mail.Date =  System.DateTime.UtcNow;

Is that the proper way? My mail is showing up on the recipient's end as if it had been sent five hours after it was actually sent. Mail sent at 3:53PM is being displayed in the mail clients as mail sent at 8:53PM.

Sender and Recipient are in the same timezone, and the timezone is correctly set in the recipients' mail clients to US/Eastern.

Here's an example header (with some of the values xxx'd or 000'd)

The mail.Date property is taken in local time.

Please use this code instead:

mail.Date = DateTime.Now;
