Question

我有一个Windows服务，它通过从数据库中检索记录来发送电子邮件。 Windows服务运行的服务帐户是该计算机上的本地管理员。我遇到的问题是某种程度上Windows服务设法发送一些电子邮件与pdf附件存在于Windows服务所在的本地服务器上，对于大多数人我收到一条错误消息：

Invalid Mail Attachment

可能导致它的真正困难是什么？我应该从哪里开始看？

由于

Try

        ' Initialize new mail message class
        Dim objEmailMessage As New System.Net.Mail.MailMessage(EmailOutboxEntity.EmailFrom, EmailOutboxEntity.EmailTo)

        ' Set the email parameters
        objEmailMessage.Subject = EmailOutboxEntity.EmailSubject
        objEmailMessage.Body = EmailOutboxEntity.EmailBody

        ' Check if attachments have been specified
        If Not EmailOutboxEntity.TestOriginalFieldValueForNull(EmailOutboxFieldIndex.EmailAttachements) Then

            ' Get an array of attachment file names to send
            Dim arrAttachment As String() = Split(EmailOutboxEntity.EmailAttachements, CONST_AttachmentSeparator)

            ' Step through each filename and attach it to the email
            For Each strAttachment As String In arrAttachment

                ' Attach the current file to the email
                objEmailMessage.Attachments.Add(New System.Net.Mail.Attachment(strAttachment))

            Next

        End If

        ' Set the SMTP server
        Dim mailServer As New System.Net.Mail.SmtpClient(pstrSMTPServer)

        ' Send the message
        mailServer.Send(objEmailMessage)

    Catch errException As Exception

        ' Throw an exception indicating the email failed to send
        Throw New EmailOutboxManagerException(errException.Message, "Test Failed to send email, got the following error instead:")

    End Try

抱歉，伙计们，因为我已经找到答案，这是我的错，因为我在不同的服务器上运行两个不同版本的Windows服务，他们都从数据库中获取附件，并且路径存在于一台服务器上保存文件的位置，而不是其他服务器上的文件，这就是为什么有些电子邮件被管理好发送的原因。

邮件附件无效
