I had a use lose 20 folders on their mail account. I was able to pull them back from a restore and dumped them all back on the server in her Maildir. The problem is she doesn't see them on her Thunderbird or Outlook client. I checked to make sure I put them back into the correct directory and I did as well as verify permissions aren't weird. I then noticed a file called 'subscriptions' in her Maildir directory. She appears to only be seeing folders that are listed in this 'subscriptions' file. My question is how do I update this file? If I delete it, will Dovecot re-generate the file with the correct subscription entries? I don't understand what to do but I'm hoping I don't have to edit the file by hand...that seems way too cumbersome.
