5.9.2.2. Email Attachments
The EmailAttachment
object is a wrapper that holds the attachment as a byte array (the data
field), the file name (the name
field), and, if necessary, the attachment identifier which is unique for this message (the optional but useful contentId
field).
The attachment identifier may be used to insert images in the message body. For this, a unique contentId
(for example, myPic
) is specified when creating EmailAttachment
. Expression like cid:myPic
can be used as a path to insert the attachment in the message body. So, to insert an image you can specify the following HTML element:
<img src="cid:myPic"/>
