Python: synchronization: update only newly added items, not updated items

[marlemion]

Hi there,

is there a way to use the python synchronisation to react only on folder state changes where new mails where added? I use this feature to more or less get a live view of the contents of a specific inbox. But when I the status of an item is updated (a flag is added etc) it is processed as it where added newly to the list. Is there a way to distinguish between updated and newly added items?

Thanks!
