Desactivate automatic flag by WM in IMAP port

Hi every body,

We use 10.5

We configure email port in IMAP.
But port after processing add flagg SEEN and certainly FLAGGED
I find this topic : Flag after processing mail (i can t add link in post !)
but no answer to how desactivate this operation.

When we look java documentation, add flag is optionnal and add in developpement.
Do you have a solution for just have list off new email and no flag this ?

The topic referred is Flag after processing mail - Forum - webMethods - Software AG Tech Community & Forums , doesn’t seem to have a resolution , linking here.
