I’ve found a new issue in the IMAP functionality of Kopano Core when using Thunderbird.
First, the affected Version is core-8.3.0~788_104.1. On core-8.3.0~694_76.1 everything seems to be ok.
The problem: When the user opens a Folder like Inbox, sometimes all emails are shown. Mostly there is only one email! When the user clicks on another folder and after that back to the first one, Thunderbird mostly shows all mails. But: Everytime Thunderbird seems to reload all Headers of the mails stored in the actual folder.
For now I’ve “dirty” downgraded to core-8.3.0~694_76.1 - everything is okay for now. But it took many hours to find out that there must be an error in Kopano. For debugging I tried to log the error, but there where no useful information in debug-logfile. Just a big amount of email headers.
I appreciate your help and information if the problem is confirmed and/or solved.
