thunderbird scans file system with imap
I run my own mail server on Solaris, and I use imap on the clients, Thunderbird on Solaris and MacOS X, Apple mail on my wifes iMac and our iOS devices.
The imapd server is WU 2007f, but used to be 2004g.
After upgrading TB on my MacBook from 31.8 to 38.x (any 38 version) I noticed that TB was apparently reading a lot from the server, and as I was over a slow 4G connection I eventually reverted to 31.8.
I've tried to debug the issue and by snooping the network and trussing the imapd daemon I see that TB 38 apparenly scans the entire file system, not just the configured mailboxes and local archives.
I've tried setting up a fresh mail account, in case I had some strange settings for my account, but it behaves the same.
None of the other clients behave like this, and 31.8 on the mac, and 31.6 on solaris is not showing this behavior.
Is there something I'm missing, or is this a new bug with 38?
Thanks, Thomas

The entire file system of what? server? Workstation?
The server.
I think you better file that one as a bug. https://bugzilla.mozilla.org/
I do not know even how Thunderbird could do that. Hence file a bug. Perhaps someone over in the developer world can shed light.
After checking out the snoop again, I noticed that TB listed "#ftp" on the imap connection right before the big scan began, and it turns out that there is a standard user on solaris "ftp", which uses "/" as the home directory.
The standard server settings includes "#ftp" for the public namespace, and after removing that in the settings it no longer does this scan.
This setting was there already in 31.x, but it seems it didn't scan that before.
So problem solved!
If you would, I think file a bug anyway, even though you have resolution, it is a non optimal situation that sees a full scan initiated. If nothing else it will slow things down. Perhaps a lot. At worst it is a security issue.
