Question

我正在将此经典ASP应用程序移至AWS并使用AWS SES SMTP发送站点电子邮件（自动，发布注册电子邮件）。

所以，下面的代码有效，但是当电子邮件到达时它会被截断（不完整）？

邮件功能：

Function Sendmail(Sender, Subject, Recipient, Body)
	dim myMail, strServer
	strServer = Request.ServerVariables("server_name")
	if strServer <> "localhost" then
	  Set myMail=Server.CreateObject("CDO.Message")
	  myMail.Subject=Subject
	  myMail.From=Sender
	  myMail.To=Recipient
	  myMail.HTMLBody=Body
	  myMail.Configuration.Fields.Item _
	  ("http://schemas.microsoft.com/cdo/configuration/sendusing")=2
	  'Name or IP of remote SMTP server
	  myMail.Configuration.Fields.Item _
	  ("http://schemas.microsoft.com/cdo/configuration/smtpserver")="email-smtp.us-east-1.amazonaws.com"
	  'Server port
	  myMail.Configuration.Fields.Item _
	  ("http://schemas.microsoft.com/cdo/configuration/smtpserverport")=465
	  'requires authentication
	  myMail.Configuration.Fields.Item _
	  ("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate")=1
	  'username
	  myMail.Configuration.Fields.Item _
	  ("http://schemas.microsoft.com/cdo/configuration/sendusername")="a username"
	  'password
	  myMail.Configuration.Fields.Item _
	  ("http://schemas.microsoft.com/cdo/configuration/sendpassword")="a password"
	  'startTLS
	  myMail.Configuration.Fields.Item _
	  ("http://schemas.microsoft.com/cdo/configuration/smtpusessl")=true						
	  myMail.Configuration.Fields.Update
	  myMail.Send
	  set myMail=nothing
	end if	
End function

邮件正文

总是在同一地点截断？

我似乎无法追踪这个？是我的功能或邮件正文中的错误？这是AWS的限制吗？

感谢您的想法，

Answer 1

当电子邮件的某一行超过某个服务器定义的长度时，SMTP服务器可能会抛出“Line too long”错误。由于您的邮件总是在同一位置截断，请尝试在邮件正文中插入换行符。我知道AWS SES SMTP可以返回此error，但我不确定该限制是什么。这是一个相关的conversation，它有类似的错误和CDO供参考。

Answer 2

CDO默认使用7bit进行内容传输编码，但不会截断长行。

您不需要用户定义的功能，但为邮件正文指定了适当的内容传输编码。

8bit，quoted-printable和base64是标准转移编码，可以处理长线。

'...
myMail.Configuration.Fields.Update
myMail.HTMLBodyPart.ContentTransferEncoding = "8bit"
myMail.Send
'...

通过AWS的ASP，vbscript，CDO电子邮件被截断了吗？
