Hi all,

Long story short, I'd like to configure a folder containing:

INBOX (some other folders)

-> unseen emails from these folders + all other emails (also seen) from the same thread -> seen emails from these folders, but only the recent ones + all other emails from the same thread

I tried:

inthread refs (or (or recent unseen) recent )

 inthread refs unseen

inthread refs (or unseen ( recent seen) )

inthread refs recent unseen

inthread refs unseen

#inthread refs recent (or unseen )

inthread refs (recent seen (or unseen ))

(inthread refs (or unseen) recent seen)

#( inthread refs (or (or recent unseen) flagged) )

without success.

Where could I find proper,understandable doc for this? Could anybody help me on configuring such rule(s) ?

Thanks a lot in adavance,

Pierre
