Email with mapi: Body message

I had writen a function to send an email from Vb using MAPI functions. The code is shown below:

MAPISession1.SignOn
With MAPIMessages1
.SessionID = MAPISession1.SessionID
.MsgIndex = -1
.Compose
.RecipDisplayName = ccC
.MsgSubject = cS
.MsgNoteText = ""
.AttachmentName = Right(cDestino, 16)
.AttachmentPathName = cDestino
.Send
End With
MAPISession1.SignOff

My default email app is Incredimail.
It works fine, but always I get the same unexpected information in the body message:
--------------Boundary-00=_2Z56N0X1VA4000000000
Content-Type: Text/Plain
Content-Transfer-Encoding:


--------------Boundary-00=_2Z56N0X1VA4000000000--

What's wrong? How I can supress that message?

Thanks.

I know nothing about Incredimail.

You need to identify whether its putting the extra lines into the message when it creates it (i.e. try sending using MAPI to Incredimail to another e-mail system and see if the lines are present); or whether its when Incredimail receives the MAPI created message (send using MAPI using a different sending mail system - like Outlook Express).

Then you can [help to] identify whether its your coding or your e-mail system.

Thank you for your answer.

I've tried with OE and no messages... so this occurs only in Incredimail

So it sounds like an error in the way Incredimail handles simpleMAPI commands.
