How can I add an attachment to a message?
To attach files to your email messages, do the following:
NOTE: When attaching files to your email message, they must be encoded and in doing so, will increase in size. The attachments sent with email have to be translated into a different format so that other email programs can read it. This type of transformation will add about 33% to the original size of the attachment. Therefore, due to the translation a 2MB attachment may turn into a 2.66MB email after encoding.
