我正在使用以下方法使用SMTP从Python发送邮件.这是正确的使用方法还是我遗失了？
from smtplib import SMTP
import datetime
debuglevel = 0
smtp = SMTP()
smtp.set_debuglevel(debuglevel)
smtp.connect('YOUR.MAIL.SERVER', 26)
smtp.login('USERNAME@DOMAIN', 'PASSWORD')
from_addr = "John Doe <john@doe.net>"
to_addr = "foo@bar.com"
subj = "hello"
date = datetime.datetime.now().strftime( "%d/%m/%Y %H:%M" )
message_text = "Hello\nThis is a mail from your server\n\nBye\n"
msg = "From: %s\nTo: %s\nSubject: %s\nDate: %s\n\n%s"
% ( from_addr, to_addr, subj, date, message_text )
smtp.sendmail(from_addr, to_addr, msg)
smtp.quit()
我正在编写一个程序来将文件附加到电子邮件中.目前我正在使用FileStream磁盘保存文件,然后我使用
System.Net.Mail.MailMessage.Attachments.Add(
new System.Net.Mail.Attachment("file name"));
我不想将文件存储在磁盘中,我想将文件存储在内存中,并从内存流传递给它Attachment.
我有一个C#应用程序,它使用SMTP通过Exchange 2007服务器通过电子邮件发送Excel电子表格报告.这些适用于Outlook用户,但对于Thunderbird和Blackberry用户,附件已重命名为"第1.2部分".
我发现这篇文章描述了这个问题,但似乎没有给我一个解决方法.我无法控制Exchange服务器,因此无法在那里进行更改.我能在C#端做什么吗？我尝试过对身体使用短文件名和HTML编码,但两者都没有区别.
我的邮件发送代码就是这样:
public static void SendMail(string recipient, string subject, string body, string attachmentFilename)
{
SmtpClient smtpClient = new SmtpClient();
NetworkCredential basicCredential = new NetworkCredential(MailConst.Username, MailConst.Password);
MailMessage message = new MailMessage();
MailAddress fromAddress = new MailAddress(MailConst.Username);
// setup up the host, increase the timeout to 5 minutes
smtpClient.Host = MailConst.SmtpServer;
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = basicCredential;
smtpClient.Timeout = (60 * 5 * 1000);
message.From = fromAddress;
message.Subject = subject;
message.IsBodyHtml = false;
message.Body = body;
message.To.Add(recipient);
if …我正在使用该SmtpClient库使用以下内容发送电子邮件:
SmtpClient client = new SmtpClient();
client.Host = "hostname";
client.Port = 465;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.EnableSsl = true;
client.Credentials = new NetworkCredential("User", "Pass);
client.Send("from@hostname", "to@hostname", "Subject", "Body");
代码在我的测试环境中工作正常,但是当我使用生产SMTP服务器时,代码失败并显示SmtpException"发送邮件失败".内部IOException"无法从传输连接读取数据:net_io_connectionclosed".
我已经确认防火墙不是问题.端口在客户端和服务器之间打开很好.我不确定还有什么可能引发这个错误.
通过电子邮件将图像作为嵌入图像发送到正文中时出现问题.图像文件显示为附件,但是内嵌图像部分显示为红色x.
这是我到目前为止所拥有的
LinkedResource inline = new LinkedResource(filePath);
inline.ContentId = Guid.NewGuid().ToString();
MailMessage mail = new MailMessage();
Attachment att = new Attachment(filePath);
att.ContentDisposition.Inline = true;
mail.From = from_email;
mail.To.Add(data.email);
mail.Subject = "Client: " + data.client_id + " Has Sent You A Screenshot";
mail.Body = String.Format(
"<h3>Client: " + data.client_id + " Has Sent You A Screenshot</h3>" +
@"<img src=""cid:{0}"" />", inline.ContentId);
mail.IsBodyHtml = true;
mail.Attachments.Add(att);
我正在使用我的Gmail帐户并smtp.gmail.com在我的网络应用程序中测试和发送电子邮件.当我的Gmail帐户启用双因素身份验证时,它无法发送电子邮件,但是当我关闭我的Gmail帐户的双因素身份验证时,该网络应用程序会成功发送电子邮件.感谢任何建议.
我是ASP.NET C#领域的新手.我打算通过ASP.NET C#发送邮件,这是我的ISP的SMTP地址:
smtp-proxy.tm.net.my
以下是我尝试做的,但失败了.

我在localhost上运行它,所以我正在做什么错误发送它.
当我发送按钮时,它给出了一个错误
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.
