When trying to send mail through the SMTP server, an error message is generated in the e-mail client indicating that the server cannot be found or the server terminated the connection. Certain ISPs (noteably SBC and Earthlink) block outgoing mail that is not sent through their servers.
One pound of fat is equal to about 3500 calories. That means that if you eat an extra 350 calories of food a day, which is about equal to a large piece of cake or a medium milkshake, you would gain an extra pound about every 10 days (350x10). Or you would gain a pound in about 20 days if you eat or drank an extra 175 calories a day (175x20).
Gaining Weight. In order to gain one pound, you must consume an additional 3500 calories. By increasing your intake by 500 to 1000 calories per day, you can expect to gain 1 to 2 pounds per week; however, a higher calorie diet may cause an increase in metabolism, which actually may slow weight gain. Thus, aim for a weekly weight gain between 1/2 pound to 1 pound, and monitor your weight weekly.
