Extracting all attachments from email message
GroupDocs.Watermark allows you to get the information about the attachments in an email message. Below is the code snippet for extracting attachments from Email.
advanced_usage.add_watermarks_to_email_attachments.EmailExtractAllAttachments
EmailLoadOptions loadOptions = new EmailLoadOptions();
// Constants.InMessageMsg is an absolute or relative path to your document. Ex: "C:\\Docs\\message.msg"
Watermarker watermarker = new Watermarker(Constants.InMessageMsg, loadOptions);
EmailContent content = watermarker.getContent(EmailContent.class);
for (EmailAttachment attachment : content.getAttachments())
{
System.out.println("Name: " + attachment.getName());
System.out.println("File format: " + attachment.getDocumentInfo().getFileType());
FileOutputStream outputStream = new FileOutputStream(Constants.OutputPath + "\\" + attachment.getName());
outputStream.write(attachment.getContent());
outputStream.close();
}
watermarker.close();
Removing particular attachment from email message
Using GroupDocs.Watermark, you can remove any particular attachment from an email message. Below is the code for removing specific attachment:
advanced_usage.add_watermarks_to_email_attachments.EmailRemoveAttachment
EmailLoadOptions loadOptions = new EmailLoadOptions();
// Constants.InMessageMsg is an absolute or relative path to your document. Ex: "C:\\Docs\\message.msg"
Watermarker watermarker = new Watermarker(Constants.InMessageMsg, loadOptions);
EmailContent content = watermarker.getContent(EmailContent.class);
for (int i = content.getAttachments().getCount() - 1; i >= 0; i--)
{
EmailAttachment attachment = content.getAttachments().get_Item(i);
// Remove all attached files with a particular name and format
if (attachment.getName().contains("sample") && attachment.getDocumentInfo().getFileType() == FileType.DOCX)
{
content.getAttachments().removeAt(i);
}
}
// Save changes
watermarker.save(Constants.OutMessageMsg);
watermarker.close();
Adding attachment to email message
You can also add attachments to the email messages using GroupDocs.Watermark. Following is the code sample for adding an attachment:
advanced_usage.add_watermarks_to_email_attachments.EmailAddAttachment
EmailLoadOptions loadOptions = new EmailLoadOptions();
// Constants.InMessageMsg is an absolute or relative path to your document. Ex: "C:\\Docs\\message.msg"
Watermarker watermarker = new Watermarker(Constants.InMessageMsg, loadOptions);
EmailContent content = watermarker.getContent(EmailContent.class);
File attachmentFile = new File(Constants.InSampleMsg);
byte[] attachmentBytes = new byte[(int) attachmentFile.length()];
InputStream attachmentInputStream = new FileInputStream(attachmentFile);
attachmentInputStream.read(attachmentBytes);
attachmentInputStream.close();
content.getAttachments().add(attachmentBytes, "sample.msg");
// Save changes
watermarker.save(Constants.OutMessageMsg);
watermarker.close();
