missing emails

If you have a pop-up device configured with the “leave a copy of messages on the server” option unchecked, emails will be automatically deleted from the server after they are downloaded to your device or software. As such, if you have additional pop or imap devices that are configured to send and receive emails to/from the same email account when these devices connect to the server, emails downloaded by the pop device will no longer be available to download from the server.

The same can be said for popup accounts that are configured to delete copies from the server after (x / 10 / 14) number of days. if there is another device that syncs with the server via imap protocol, when emails are deleted from the server after (x / 10 / 14) number of days, the imap device will reflect this change, resulting in emails “go away”. lost”. In this case, emails will need to be fetched locally on the device connecting via the pop protocol.
