通过SMTP发送带附件,纯文本/文本和文本/ hml的电子邮件

我的目标:使用普通/文本,文本/ html和附件通过SMTP发送交易电子邮件.

我的代码:用JavaMail实现

我的问题:它在hotmail或outlook上看起来很好.但是在gmail上,如果它是带有.txt附件的电子邮件,它就不会正确显示邮件正文(如果附件是图像,它可以正常工作)

任何帮助将受到高度赞赏.

这是我的原始SMTP输出:

如何删除图像作为附件,但显示在电子邮件正文中

我找到了这个解决方案,用于在电子邮件正文中显示图像: 将图像添加到电子邮件正文中

它工作正常,但它也添加图像作为电子邮件的附件.

Attachment inlineLogo = new Attachment(EmailLogo.ImageUrl);
mailMsg.Attachments.Add(inlineLogo);
string contentID = "Image";
inlineLogo.ContentId = contentID;

//To make the image display as inline and not as attachment
inlineLogo.ContentDisposition.Inline = true;
inlineLogo.ContentDisposition.DispositionType = DispositionTypeNames.Inline;

//To embed image in email
mailMsg.Body = "<htm><body> <img height=\"49\" width=\"169\" src=\"cid:" + contentID + "\"> </body></html>";

Gmail会在HTML电子邮件的图片上显示下载图标

我们有一个Html Builder,允许您为电子邮件创建响应式HTML.我们正在使用第三方引擎批量发送电子邮件.问题是,当电子邮件在Gmail收件箱正在运行结束,它显示一些图像(不是全部)的下载图标,而相对于没有下载图标的图像时,其生成的html是一样的.

悬停下载图标

为什么gmail会在电子邮件中添加图像的下载图标.看起来像处理图像像附件.任何信息,修复或建议表示赞赏？这是我们发送的生成的html-

如何使用Python将大文件附加到电子邮件-Gmail API

我正在尝试发送带有附件（最好是多个附件）的电子邮件，这些附件大于10 MB并且小于25 MB的总限制。我提到10 MB的原因是，这似乎是正常的附加文件方式停止起作用时得到的下限Error 10053。

我在文档中已经读到，做到这一点的最佳方法是使用可恢复的上载方法，但我无法使其正常工作，也无法在Python中找到任何好的示例。关于此的大多数SO问题都只是链接回到没有Python示例的文档，否则它们的代码会导致其他错误。

我正在寻找Python中的解释，因为我想确保自己理解正确。

我浏览过的问题：
