In my C3PO plugin I need to get the message ID (or the complete message)
of the message that is sent by clicking the "send" bnutton in the
composer window.
For this I catch the send token and execute it myself again because when
the execute comes back, an outgoing mail has been created and I simply
look for it by getting the last message in mailbox with ObjAPI.
This works pretty good for most systems, on other systems it does not
work because after the item send execute comes back no message has been
created on the outgoing box.

Are there any known flaws doing this sequence or is there a better way
of doing what I need to do?

Best regards,
