我采用了.net 的自带组件 System.Web.Mail.MailMessage发送邮件,主要是在客户注册网站成功的时候发条欢迎邮件,最近邮件无法发送了,看了下腾讯smtp邮件配置,所有的邮件发送都换成ssl了,之前用的是25端口,现在换成了465或587,于是修改代码如下:
MailMessage msgMail = new MailMessage("发件箱", "收件箱", "邮件标题", "邮件内容",2); SmtpClient smtp = new SmtpClient("smtp.qq.com", 465,2); smtp.EnableSsl = true; smtp.DeliveryMethod = SmtpDeliveryMethod.Network; smtp.Credentials = new System.Net.NetworkCredential("发件箱", "发件箱登录密码",2); try { smtp.Send(msgMail,2); } catch (Exception ex) { Console.WriteLine("发送完毕......",2); }
这样还是不行,报操作已超时错误 在国外的技术网站上看到一句话System.Net.Mail支持Explicit SSL但是不支持Implicit SSL,然后查了下关于这两个模式的资料,我按照我理解的说一下:
Explicit SSL 发起于未加密的25,然后进行一个starttl握手,最终切换到加密的连接。
Implicit SSL 直接从指定的端口发起starttl握手。
既然指定了端口,那么应该就是使用了Implicit SSL,不知道微软什么时候能更新下System.net.mail,System.net.mail能在邮件中嵌入图片的。问题到了这里,那是不是就没有办法利用腾讯邮箱发邮件了呢?答案肯定是否定的,foxmail不就可以配置发送邮件吗?我们可以利用CDO.Message和System.web.mail发送邮件。
详见我下面的2篇文章:
System.Web.Mail.MailMessage mail = new System.Web.Mail.MailMessage(,2); try { mail.To = "收件人邮箱"; mail.From = "发件人邮箱"; mail.Subject = "subject"; mail.BodyFormat = System.Web.Mail.MailFormat.Html; mail.Body = "<font color=‘red‘>body</font>"; mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1",2); //basic authentication mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "发件人邮箱",2); //set your username here mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "发件人邮箱密码",2); //set your password here mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", 465,2);//set port mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpusessl", "true",2);//set is ssl System.Web.Mail.SmtpMail.SmtpServer = "smtp.qq.com"; System.Web.Mail.SmtpMail.Send(mail,2); //return true; } catch (Exception ex) { ex.ToString(,2); }
如何引用CDO.Message? cod.message的引用位置: C:\Windows\System32\cdosys.dll
CDO.Message objMail = new CDO.Message(,2); try { objMail.To = "接收邮件账号"; objMail.From = "发送邮件账号"; objMail.Subject = "subject";//邮件主题string strHTML = @""; strHTML = strHTML + "这里可以填写html内容"; objMail.HTMLBody = strHTML;//邮件内容 objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/smtpserverport"].Value = 465;//设置端口 objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/smtpserver"].Value = "smtp.qq.com"; objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/sendemailaddress"].Value = "发送邮件账号"; objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/smtpuserreplyemailaddress"].Value = "发送邮件账号"; objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/smtpaccountname"].Value = "发送邮件账号"; objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/sendusername"].Value = "发送邮件账号"; objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/sendpassword"].Value = "发送邮件账号登录密码"; objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/sendusing"].Value = 2; objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/smtpauthenticate"].Value = 1; objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/smtpusessl"].Value = "true";//这一句指示是否使用ssl objMail.Configuration.Fields.Update(,2); objMail.Send(,2); } catch (Exception ex) { throw ex; } finally { } System.Runtime.InteropServices.Marshal.ReleaseComObject(objMail,2); objMail = null;
