email package - how to get message body

[Mario Premke]

Hi,
possibly a stupid question, but anyhow, I can not find a method in the
email package to get an email body ( I mean the text seperated from
the header by one blank line). I can parse an email file so that I
have the object model of an email and play around with it (alter
header properties, etc. ) - what I wonder now is if there is a method
which returns the simple text message ???

Thans in advance  
Mario
