Question

从Windows服务发送电子邮件时，我遇到上述错误。非常感谢您的建议。

SmtpClient smtpClient = new SmtpClient();
MailMessage mailMsg = this.ComposeMailMessage();
smtpClient.Send(mailMsg);

配置

<system.net>
    <mailSettings>
        <smtp from="user1@mycompany.com" deliveryMethod="Network">
            <network host="smtpsvr.mycompany.com" port="25" defaultCredentials="true" />
        </smtp>
    </mailSettings>
</system.net>

Answer 1

也许我的搜索不是你的答案，但试试这个（避免使用IIS）：

try
{
    // To
    MailMessage mailMsg = new MailMessage();
    mailMsg.To.Add(to_Address);

    // From
    MailAddress mailAddress = new MailAddress(from_address);
    mailMsg.From = mailAddress;

    // Subject and Body
    mailMsg.Subject = subject;
    mailMsg.Body    = body;

    // Init SmtpClient and send
    SmtpClient smtpClient = new SmtpClient(smtp_server, port);
    // System.Net.NetworkCredential credentials =
    //    new System.Net.NetworkCredential(smtp_user, smtp_pwd);
    // smtpClient.Credentials = credentials;

    smtpClient.Send(mailMsg);
}
catch (Exception ex)
{
    Console.WriteLine( ex.Message );
}

Answer 2

您可能需要手动设置SmtpClient PickupDirectory。

在Lukas Pokorny的回答中有一个如何做到这一点的例子：

Cannot get IIS pickup directory

Answer 3

尝试将以下行添加到您的程序中。此行需要在桌面上运行IIS Admin和SMTP服务。

smtpClient.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;

所以它会变成这样的

SmtpClient smtpClient = new SmtpClient();
MailMessage mailMsg = this.ComposeMailMessage();
smtpClient.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;
smtpClient.Send(mailMsg);

无法获取IIS拾取目录（从Windows服务）
