以下网站是必读"网站，适用于试图在.NET Framework中发送邮件的人，因为它包含对您可能遇到的问题的大多数答案.

对于有关邮件进入垃圾邮件"的问题，首先，不要发送邮件，使人们单击发送到垃圾文件夹".直接地.如果报告您的电子邮件域正在从多个人发送垃圾邮件并被服务器阻止，则没有 可以帮助您的技术.

此外，在自动发送电子邮件之前，请先尝试通过垃圾邮件检查程序运行邮件内容，以将检测标记降低到尽可能低的水平. (我个人最喜欢的是 SpamAssassin ，尽管仅在* nix系统上可用.如果您的邮件内容不是机密信息，则可能需要在免费评分标记服务(例如 http://spamcheck.postmarkapp.com/)

在将电子邮件发送给内容完全相同的同一主机时，不要多次发送邮件，而应充分利用密件抄送将其发送一次，这样可以减少系统被标记为垃圾邮件的可能性(尽管我知道这个矛盾 一些电子邮件服务器管理员添加规则以处理来自外部的所有邮件，即收据的电子邮件地址未出现在收件人"中.或"CC"字段将被标记为垃圾邮件

如果必须将邮件重复发送到主机，请确保每15分钟发送30封邮件，而不是一次发送所有邮件.实现每个主机"任务队列来管理这一点将是一个好主意. (毫无疑问，发送 一口气完成所有操作，都会使您的SMTP主机被服务器阻止，但是如何慢速"运行?够了，再次取决于邮件服务器的配置)

还有其他相关提示，例如 SPF 我不会一一经历.您选择的垃圾邮件标记检查器的文档中应清楚概述这些信息.

If you are using mail.mybluefile.com it seems you may be using SMTP

The following site is a "must read" for people trying to send mail in .NET framework as it contains most answers to possible problems you'd encounter.

http://www.systemnetmail.com/faq/3.3.4.aspx

For the problem regarding "mail goes to spam", first, don't send mail that people will click "send to junk folder" directly. If your email domain is reported to be sending spam from multiple people and blocked by the server, there's no technique that can help you.

Also, before sending emails automatically, try run the mail content through the spam checkers first to reduce the detection mark to as low as possible. (My personal favorite is SpamAssassin, although it's available on *nix systems only. If your mail content is not confidential you may want to run it on free score marking services like http://spamcheck.postmarkapp.com/ )

When sending email to the same host with exactly the same content, instead of sending mail multiple time, make good use of BCC to send it only once will reduce the likelyhood to get the system marked as spam) (although on the contravory, I know some email server admins add rule to treat all mails from outside that the receipent's email address not appear in "To" or "CC" fields will be marked as spam)

If you have to send mail repetitively to a host, make sure you send it on like 30 mails per 15 minute instead of sending them all at once. Implementing "per host" task queue to manage this would be a good idea. (There's no doubt sending everything in one go will make your SMTP host be blocked by server, but how "slow" is enough is again varies by mail server configuration)

There are other related tips like SPF that I will not go through one by one. These information should be clearly outlined in the documentation of the spam mark checker of your choice.
