Sending e-mail from gmail account using asp.net (optionally with enabled SSL) is really easy:

in the web.config:

<system.net>
<mailSettings>
<smtp from="YOUR_ACCOUNT@gmail.com">
<network host="smtp.gmail.com"
port="587"
userName="YOUR_ACCOUNT@gmail.com"
password="YOUR_PASSWORD" />
</smtp>
</mailSettings>
</system.net>

* you can add system.net below the </connectionStrings> tag.

* change YOUR_ACCOUNT and YOUR_PASSWORD with suitable values.

here's a function to send emails:

...

using System.Net.Mail;

...

protected void SendMail(string aSendTo, string aSubject, string aBody, bool aIsHtml, bool aEnableSsl)
{
MailMessage mailMessage;
SmtpClient smtpClient;

try
{
mailMessage = new MailMessage();

mailMessage.To.Add(aSendTo);

mailMessage.Subject = aSubject;
mailMessage.Body = aBody;
mailMessage.IsBodyHtml = aIsHtml;

// send e-mail with the attached program
smtpClient = new SmtpClient();
smtpClient.EnableSsl = aEnableSsl;

smtpClient.Send(mailMessage);

}
catch (Exception ex)
{
// handle the exception
}

}

* if you want the SendMail to send e-mails to multiple mails, just change aSendTo to be List<string> and for each element call mailMessage.To.Add method

* if you want SSL to be enabled just call the function with param aEnableSsl = true.

* The examle should works for asp.net 2.0, too.

you can just copy-paste the function in your code and that's all :)
