[IMAP "Fetch Emails"] Fetch Since feature is applied also to "Sent" inbox?

[183p]

Dear all,

about "Fetch Since" feature in IMAP > Fetch Emails, when enabled, this option is applied also to "Sent" Folder, when configured in "Monitored Folders"? Or only to Inbox folder?

Now it seems to be applied only to "Inbox", and not to other folders configured in "Monitored Folders", eg. "Sent" folders.

Thank's a lot
