I would like to use a part of a mail as a variable in a job, so I configure the tFileInputMail with a column content that refers to the "body" Mail part.
But when I run it I obtain the following value:

------=_Part_0_18163514.1205836518906
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

test
------=_Part_0_18163514.1205836518906--

And I want to use only the variable test
Is there a different MailPart declaration to use only the text?
Thanks
