我需要创建一个连接到IMAP服务器并侦听新邮件的服务(或控制台)应用程序.我目前正在尝试使用MailKit,但我无法从文档中找出如何实现这一目标.

我最接近的是这篇文章.从我所看到的,这篇文章是将连接设置为IDLE模式,偶尔发送NoOP以尝试保持连接活动.我不完全清楚的是如何收到新的邮件通知.

MailKit文档似乎表明有一个Alert事件可用.我试过挂钩,但这似乎没有解决任何问题.

这是我尝试过的:

    var cts = new CancellationTokenSource();
    testIDLEMailNotification(cts.Token);

    ...

    private static void testIDLEMailNotification(CancellationToken token)
    {
        using (var client = ClientCreateAndConnect(token))
        {
            while(!token.IsCancellationRequested)
            {
                using (var done = new CancellationTokenSource())
                {
                    using (var timer = new System.Timers.Timer(9 * 60 * 1000))
                    {
                        timer.Elapsed += (sender, e) => done.Cancel();
                        timer.AutoReset = false;
                        timer.Enabled = true;
                        try
                        {
                            client.Idle(done.Token, token);
                            client.NoOp(token);

                        }
                        catch (OperationCanceledException)
                        {
                            break;
                        }
                    }
                }
            }
        }
    }

    private static ImapClient ClientCreateAndConnect(CancellationToken token)
    {

我正在使用mimekit接收和发送我的项目的邮件.我发送收到的邮件进行了一些修改(来自和来自部分).现在我需要修改身体部分.我将用asterix字符替换特定的单词.每封邮件的具体文字不同.邮件可以是任何格式.你可以看到我找到了我想要的但我不知道如何更换没有任何错误？

我尝试对在 Azure 门户上创建的 O365 应用程序进行身份验证，但它无法按预期工作。

以下代码运行良好，但它使用登录名/密码，并且 Microsoft 不推荐。（在这里找到https://github.com/jstedfast/MailKit/issues/989）

var scopes = new[] { "https://outlook.office365.com/IMAP.AccessAsUser.All" };

var confidentialClientApplication = PublicClientApplicationBuilder.Create(_clientId).WithAuthority(AadAuthorityAudience.AzureAdMultipleOrgs).Build();

SecureString securePassword = new NetworkCredential("", _userPassword).SecurePassword;
var acquireTokenByUsernamePasswordParameterBuilder = confidentialClientApplication.AcquireTokenByUsernamePassword(scopes, _userMail, securePassword);
var authenticationResult = acquireTokenByUsernamePasswordParameterBuilder.ExecuteAsync().Result;

if (_debugCall)
{
imapClient = new ImapClient(new ProtocolLogger(_configurationId + "_IMAP_" + DateTime.Now.ToString("yyyyMMddHHssffff") + ".log"));
}
else
{
imapClient = new ImapClient();
}
        
imapClient.CheckCertificateRevocation = false;
imapClient.ServerCertificateValidationCallback = (s, c, h, e) => true;

imapClient.Connect(_webServiceUrl, _webServicePort, SecureSocketOptions.Auto);
imapClient.Authenticate(new SaslMechanismOAuth2(_userMail, authenticationResult.AccessToken));  

if (string.IsNullOrEmpty(_folder))
{

有人知道MailKit是否支持读取收据(读取时回复消息)？我没有在网上或Stackoverflow上找到任何东西.

我最近一直在制作自己的邮件客户端,并添加了一个接收选项,我使用mimekit和mailkit作为插件,并且能够使用应该显示内容的阅读器下载我的大部分邮件(现在它显示主题,来自,来自, ,日期)

我下载主题的方式是,...是msg.envelope.subject,msg.envelope.to但我无法下载这样的主体:(当做msg.body,msg.textbody,msg.bodyparts ,. ..他们都导致了NOTHING,它应该是空的地方,我无法下载:(

谁能帮我？

当我使用MailKit通过IMAP协议收到来自Exchange的邮件时,它缺少附件.当我做:

string.Format("Mail has {0} attachments", mime.Attachments.Count())

它报告"0",即使邮件本身包含附件(如果我在Outlook客户端中打开它,我会看到附件)​​,当我激活IMAP协议日志记录时,显然它包含一个附件:

S: X-MS-Has-Attach: yes
...
S: Content-Type: message/rfc822
S: Content-Disposition: attachment;
S:  creation-date="Thu, 07 Jan 2016 09:16:53 GMT";
S:  modification-date="Thu, 07 Jan 2016 09:16:53 GMT"
...
S: X-MS-Has-Attach:
...

有趣的是附件部分中的"S:X-MS-Has-Attach:"标题,位于服务器的同一个包中.

这是一个已知的问题,我该如何修复它以便在这些情况下我不会错过附件？它似乎只发生在一些邮件上并随机发生.

使用:MailKit 1.0.14.0 MimeKit 1.0.13.0

我发现有新的更新,但如果不能解决问题,我不会真正更新.

当 DKIM 使用 Mailkit 和 Mimekit 签署标头时，我看到一个奇怪的问题，Gmail 报告错误“dkim=neutral（正文哈希未验证）”。

我在这里做错了吗？请在下面找到我的代码和屏幕截图 附上实际收到的邮件。

        string ReturnName = "DMC12";
        string FromDomain = "backtothefuture.net";
        string FromEmail = "marty@" + FromDomain;

我在Web应用程序上使用MVC ASP.NET Core 1.1.2.我尝试使用MailKit 1.18.1.1创建联系表单.我通过电子邮件(gmail)发送联系表格信息.当我在本地构建网页时,一切都按预期工作.我第一次在本地运行程序,它给了我同样的错误,但我启用了我的邮件地址的安全设置,它开始工作.但是当我在网络上部署它时,即使我设置安全设置以启用安全性较低的应用程序,它也会给我一个这样的错误:

这是Home Controller中的SendMail方法:

public IActionResult SendMail(string name, string phone, string email, string msg)
        {

            message.To.Add(new MailboxAddress("theemailaddresswhichrecievestheinfo@gmail.com"));
            message.Subject = name;
            message.Body = new TextPart("html")
            {
                Text = "Kimden: " + name + "<br>" + "Mail adresi: " + email + "<br>" +

            {
                client.Connect("smtp.gmail.com", 587);

我正在尝试使用MailKit通过“ smtp.office365.com”发送电子邮件。这是我正在使用的代码。

using (var client = new SmtpClient(new ProtocolLogger("smtp.log")))
{
    client.ServerCertificateValidationCallback = (s, c, h, e) => true;
    client.Connect("smtp.office365.com", 587, SecureSocketOptions.SslOnConnect);
    client.Authenticate(new SaslMechanismNtlmIntegrated());
    Debug.WriteLine(client.IsAuthenticated);
    client.Send(message);
    client.Disconnect(true);
}

SaslMechanismNtlmIntegrated我从GitHub上的此评论获得的课程。

每当我运行此代码时，我都会得到一个SslHandshakeException。

One possibility is that you are trying to connect to a port which does not support SSL/TLS.

The other possibility is that the SSL certificate presented by the server is not …

I'm trying to send an email with Gmail account. I was able to send emails with yahoo, however, it doesn't work anymore, for some unknown reason. Which i posted a question about that as well, but not response.

In this instance, i'm trying to connect to a gmail account so that I can send emails, but with no luck, it fails after the Connect.

It connects successfully but doesn't authenticate at all, although I have the right credentials.

This is …
