Attachment class abstract

Represents a single email attachment.

You may specify a File, a Stream or just a String of data. cid allows you to specify the content id for html inlining.

When location is set to Location.inline The attachment (usually image) can be referenced using: cid:yourCid. For instance: <img src="cid:yourCid" />

cid must contain an @ and be inside < and >. The cid: <myImage@3.141> can then be referenced inside your html as: <img src="cid:myImage@3.141">
