Plesk问题从.Net REST API发送电子邮件

plesk-onyx smtpclient email c#

Robert Green MBA · 技术社区 · 6 年前

这是我的代码:

fromEmail = "fromEmail@gmail.com";
toEmail = "toEmail@gmail.com";
subject = "test-subject";
message = "test-message";
bccEmail= "bccEmail@gmail.com";

MailMessage mailMessage = new MailMessage(fromEmail, toEmail, subject, message);
mailMessage.Bcc.Add(bccEmail);
mailMessage.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient("smtp.1and1.com", 587);
//smtp.EnableSsl = true;
NetworkCredential credentials = new NetworkCredential(WebConfigurationManager.AppSettings["EmailUserName"], WebConfigurationManager.AppSettings["EmailPassword"]);
smtp.Credentials = credentials;
smtp.Send(mailMessage);

我有一个 200 从我的服务,但我收到了以下来自Plesk的电子邮件(注意“$”前的收件人,主题和消息(我认为这是问题,但不确定为什么它这样做)。此外,此代码在本地工作正常-在调试中并在本地IIS上运行):
