Add e-mail parts or attachments services

The following methods of the SendMsgCmd command allow users of the messaging system to attach content parts, or attachments, to messages:

public void addContentPart(byte[] msgAttachment)

This method offers a simple way to add content parts to a message. For the e-mail transport, a "content part" refers to an attachment. The msgAttachment parameter represents the content to be added to the message. Note that this must be the actual content of the part, translated into byte format.

public void addContentPart(byte[] msgAttachment , String partName, String partType)

This method gives you greater flexibility in adding content parts to a message. The msgAttachment parameter represents the content to be added to the message. The partName parameter represents a name to be used for the content part. The partType parameter represents the MIME type of the part being sent. For example, the partType for Mime Email could be 'text/html', or 'text/plain', which is the default.
