missing emails

[PuntonetSvb]

It is the second time that it happens to me that in two different installations of keyhelp, without further ado, part of the emails sent disappear, without touching anything or changing anything on the server or anything, today several months of emails sent from the account disappeared from a client, uses outlook 2019 as imap to check mail, and no device has connected to download them, and only those from the last few months have disappeared, the previous ones are still correctly

I used a dedicated server with ubuntu 20.04 in one and debian 11 in other server keyhelp is 23.0

Take a proper MUA.
