The owner is austin and group is austin before and after mounting the folder.

I have tried different times to recursively apply wrx permissions to all the folders and files but it seems like dovecot must create files that it later cannot access. Or maybe I am not understanding this correctly? Why am I getting these errors only about 1% of the time and the rest of the time it works fine? This seems to be randomly happening to various users on my server. Thanks again to all of you for your help! Austin Witmer
