restore email messages

[mr_reload]

Hello,

I am trying to restore some accidentally deleted emails from backup.
I cp -p the emails from backup to the users "new" directory
they got moved to the "cur" but don't show up in email client.
I have checked the owner and permissions, deleted courieruidb file
(it was recreated)
but still cannot see any of the restored emails.

Thanks in advance for any advice!

[mr_reload]

I am able to see the messages with tbird but not with any of the
webmail clients.
Do I need some refresh something? Delete some cache?

Thanks for any suggestions.

Some clients keep a record of which message IDs it's already viewed and
hides those from view even though they are actually there.

It would depend on which program you are using as to exactly how
to go in there and clear the indexing if that is what is going on here.
