use*_*192 64 c# smtp google-apps
我有一个标准的Google Apps帐户.我已通过Google Apps设置了自定义域名.当我使用Gmail界面时,我可以通过Google Apps成功发送和接收电子邮件.但是,我想通过代码发送电子邮件.为了尝试这个,我一直在尝试以下代码:
MailMessage mailMessage = new MailMessage();
mailMessage.To.Add("someone@somewhere.com");
mailMessage.Subject = "Test";
mailMessage.Body = "<html><body>This is a test</body></html>";
mailMessage.IsBodyHtml = true;
// Create the credentials to login to the gmail account associated with my custom domain
string sendEmailsFrom = "emailAddress@mydomain.com";
string sendEmailsFromPassword = "password";
NetworkCredential cred = new NetworkCredential(sendEmailsFrom, sendEmailsFromPassword);
SmtpClient mailClient = new SmtpClient("smtp.gmail.com", 587);
mailClient.EnableSsl = true;
mailClient.DeliveryMethod = SmtpDeliveryMethod.Network;
mailClient.UseDefaultCredentials = false;
mailClient.Timeout = 20000;
mailClient.Credentials = cred;
mailClient.Send(mailMessage);
到达Send方法时,抛出异常,指出:
"SMTP服务器需要安全连接或客户端未经过身份验证.服务器响应为:5.5.1需要身份验证."
如何通过Google通过自定义域发送电子邮件？
谢谢!

无需对代码中的所有smtp设置进行硬编码.把它们放在web.config中.这样,您可以根据需要加密这些设置,并在不重新编译应用程序的情况下即时更改它们.
<configuration>
<system.net>
<mailSettings>
<smtp from="example@domain.com" deliveryMethod="Network">
<network host="smtp.gmail.com" port="587"
userName="example@domain.com" password="password"/>
</smtp>
</mailSettings>
</system.net>
</configuration>
发送电子邮件时结束只需在SmtpClient上启用SSL:
var message = new MailMessage("navin@php.net");
// here is an important part:
message.From = new MailAddress("example@domain.com", "Mailer");
// it's superfluous part here since from address is defined in .config file
// in my example. But since you don't use .config file, you will need it.
var client = new SmtpClient();
client.EnableSsl = true;
client.Send(message);
确保您从与Gmail尝试进行身份验证的电子邮件地址发送电子邮件.
注意:从.NET 4.0开始,您可以将enableSsl ="true"插入到web.config中,而不是在代码中设置它.
这就是我在WPF 4中使用的内容
SmtpClient client = new SmtpClient();
client.Credentials = new NetworkCredential("sender_email@domain.tld", "P@$$w0rD");
client.Port = 587;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
try {
MailAddress
maFrom = new MailAddress("sender_email@domain.tld", "Sender's Name", Encoding.UTF8),
maTo = new MailAddress("recipient_email@domain2.tld", "Recipient's Name", Encoding.UTF8);
MailMessage mmsg = new MailMessage(maFrom.Address, maTo.Address);
mmsg.Body = "<html><body><h1>Some HTML Text for Test as BODY</h1></body></html>";
mmsg.BodyEncoding = Encoding.UTF8;
mmsg.IsBodyHtml = true;
mmsg.Subject = "Some Other Text as Subject";
mmsg.SubjectEncoding = Encoding.UTF8;
client.Send(mmsg);
MessageBox.Show("Done");
} catch (Exception ex) {
MessageBox.Show(ex.ToString(), ex.Message);
//throw;
}
注意防火墙和反病毒.这些令人毛骨悚然的东西往往会阻止发送电子邮 我使用McAfee Enterprise,我必须添加可执行文件名(如Bazar.exe和Bazar.vshost.exe的Bazar.*)才能发送电子邮件...
