Hello,

I created a virtual Folder that should contain all Mails from several different Folders and their subfolders. Recently I added a new folder to the dovecot-virtual file and then found that most Mails from this folder were missing. I always restartet dovecot (is this necessary?) after any change. The system is running Debian Stretch and I am using the supplied dovecot 2.2.7 (see below for output of doveconf -n).

To narrow this down I removed all other directories from the dovecot-virtual file and then found that the number of mails is correct, but most mails are the wrong ones from other directories. The dovecot-virtual file currently contains only the source directory and in the last line 4 spaces followed by the keyword "all" and a newline. Mails that where moved there after the directory was added to the virtual folder seemed to be displayed correct. If I move one Mail away from the source diectory a totally different Mail in the virtual Folder disappers. After moving the file back to the source folder it correctly appears in the virtual folder.

What might be the cause and how can I fix it?

Thanks, Frank
