Hello All,

I set up KMail with the Maildir set up to a local disk.
Settings -> Configure KMail... -> Accounts -> Receiving -> Local Folders
.local/share/local-mail
This worked. I could download email, upload email, create folders, do everything.

Set up an NFS server and now have the Maildir on the server, mounted on my /mnt.
Settings -> Configure KMail... -> Accounts -> Receiving -> Local Folders
/mnt/NFS/tileroofs/.local/share/local-mail
When I do an ls of the local-mail directory on the share, it shows all of my folders with their email contents.
KMail does not like this configuration. But I need it!

In KMail, the left-hand pane shows Local Folders, inbox, outbox, sent-mail.
And it shows none of the folders in the local-mail directory.
When I create a new folder in the left-hand pane, it instantly disappears from the left-hand pane, yet it appears in the local-mail directory on the share.

Also, when I go to "Check Mail" it gives this new error:

POP3 Account
Unable to store downloaded emails.
Invalid parent collection

As part of this process, Selinux complained, so I set this:
setsebool -P use_nfs_home_dirs 1

Any ideas what to try next?
