mime

Why webmails (like Gmail) sends MIME messages using multipart/alternative subtype (when composing in HTML) while others send HTML as MIME with text/html parts inside (without using alternative subtype)? multipart/alternative indicates that each part is an "alternative" version of the same (or similar) content, each in a different format denoted by its "Content-Type" header. The formats are ordered by how faithful they are to the original, with the least faithful first and the most faithful last. Mail-agents like Gmail know what they are doing, and convert the text/html to text/plain and put

I'm having some trouble sending a message to multiple addresses using the Gmail API. I've successfully sent a message to only one address, but get the following error when I include multiple comma-separated addresses in the 'To' field: An error occurred: https://www.googleapis.com/gmail/v1/users/me/messages/send?alt=json returned "Invalid to header"> I'm using the CreateMessage and SendMessage methods from this Gmail API guide: https://developers.google.com/gmail/api/guides/sending That guide states that the Gmail API requires messages that are RFC-2822 compliant. I again didn't have much luck

I have a database containing emails and I want to search for a specific date using the regex operator and return all emails sent on that date. I have tried this so far but it doesn't return anything. I am new to regex and am not sure if I'm querying the date correctly. db.messages.find({'headers.Date' : $regex : '2001-07-06'}}) This example below successfully returned all the emails send from the specified email address. db.messages.find({'headers.From' : { $regex : 'reservations@merriotts.com' } }); The emails contain the following information: headers { content transfer encoding, content

近年来邮件诈骗数不胜数，我们要如何避免邮件诈骗。利用科学的手段，使用 S/MIME 证书来一眼辨别邮件的真伪，让假老板无处可逃 第一张 S/MIME 证书就在这里申请了，用来保护我们邮件的安全。邮件届的 HTTPS。 首先，需要注册一个 freessl.cn 的账号 然后，从 keymanager.org 下载一个客户端，这个客户端可以很好的帮我们管理证书私钥 申请S/MIME证书 输入 freessl.cn 进入网站 选择 S/MIME 邮件证书，并输入你需要申请的证书的 邮箱地址 点击申请，会跳到后台付款的页面。注意，这里需要登录 付款完成后，订单列表，点击继续离线生成 到这一步基本，就只需要验证邮箱所有权了。它会发送一封邮件到你 这里是邮件内容，点击邮件链接即可验证 验证完成之后，回到 freessl.cn 的订单列表，你会看到订单状态已经完成。我们保存到 keymanager，整个 S/MIME 证书就申请成功了 使用S/MIME证书 S/MIME 证书是用于邮件安全的，所以大多应用场景应该是在邮件发送接收这块。不过 freessl 开发了一个功能，实现了账号的 免密登录，体验不错 首先，我们需要从 keymanager 将导出为 PFX 格式，然后双击安装到系统里 之后就可以体验 freessl.cn 的免密登录功能了 S/MIME 证书的邮件客户端的使用就自己去探索吧。

I had never run into this problem, but I cannot get a handle on a file attachment on an email. I have code that can either search the document for Embedded Objects or search a field for Embedded Objects -- neither of them are returning the file. I can see the file on the email and I can see the $FILE field which contains the file attachment. Here is the code: Function FileDetachFiles(doc As NotesDocument, fieldName As String, getFromField As Integer) As Variant On Error Goto ProcessError Dim s As NotesSession Dim db As NotesDatabase Dim rtItem As NotesRichTextItem Dim fileToExtract As String

-------------------------------------------------------------------------------------- 表单中enctype="multipart/form-data"的意思，是设置表单的MIME编码。（ 用于文件上传 ） 默认情况， 这个编码格式是application/x-www-form-urlencoded （不能用于文件上传）； 只有使用了multipart/form-data，才能完整的传递文件数据。 enctype="multipart/form-data"是上传二进制数据; form里面的input的值以2进 制的方式传过去。 form里面的input的值以2进制的方式传过去， 所以request就得不到值了。也就是说加了这段代码,用request就会传递不成功 取表单值加入数据库时，用到下面的： SmartUpload su = new SmartUpload();//新建一个SmartUpload对象 su.getRequest().getParameterValues();取数组值 su.getRequest().getParameter( );取单个参数单个值 -----------------------------------------------------------------
