Sendmail attachment without uuencode

Did you know that Sendmail relies on the uuencode utility while sending emails with attachments?

This utility converts binary data into ASCII text so that it can be sent via email. However, we can still send attachments without the uuencode in Sendmail.

This is done by specifying the attachment as a MIME attachment. It is a standard format for sending multimedia content over the Internet.

According to our experts, we can easily send an attachment without uuencode in Sendmail as seen below:

1. First, we have to create the email message with the attachment.
2. Then, we have to set the Content-type header as multipart/mixed to indicate that the email contains both text and binary data.
3. After that, add a boundary string to the Content-Type header. This helps separate the different parts of the message.
4. Next, add the message text to the email body. Then add the binary data of the attachment.
5. Then, we have to set the Content-Type of the attachment to the corresponding MIME type.
6. After that, we have to set the Content-Disposition header to the attachment.
7. Next, set the filename parameter of the Content-Disposition header to the attachment file’s name.
8. Finally, we can send the email using Sendmail.

For instance, here is a Sendmail message with an attachment without uuencode:


From: sender@bobcares.com To: recipient@bobcares.com Subject: Test email with attachment Content-Type: multipart/mixed; boundary=boundarystring --boundarystring Content-Type: text/plain Hello, This is a test mail. Please find attached the file you requested. Regards, Sender --boundarystring Content-Type: application/pdf Content-Disposition: attachment; filename=testattachmsnt.pdf [Binary data of the PDF file goes here] –boundarystring--
I

Here, the MIME type is set as “application/pdf”. In addition, “trestattachment.pdf” is the filename parameter of the Content-Disposition header.
