Hello all,
I'm not sure if this is a bug. It's probably just an upgrade note.
In summary I had no namespace section in my 2.0.17 config. When trying out
2.1rc5 no user could login because of a namespace error.
2.1rc5 adds a default namespace clause which broke my logins (It was noted in
the changelog)
I seemed to fix it by just putting this in the config file:
namespace inbox {
inbox = yes
}
Long story:
I've been recently testing dovecot against cyrus to decide where we should
go for our next mail server(s)
I loaded up the mail server with mail delivered via postfix all on dovecot
2.0.15 (I've since moved to 2.0.17)
I have three dovecot directors, two backends on the same NFS mail store.
With dovecot 2.0.xx the tester works fine (it't just a script which logins
in and emulates thunderbird when a user is idle -
without using IDLE so the client asks for mail every few minutes).
When I moved to 2.1rc5 I got namespace errors and the user can not login.
The server said:
dovecot-error.log-20120128:Jan 27 13:37:59 imap(ethab01): Error: user ethab01:
Initialization failed: namespace configuration
error: inbox=yes namespace missing
The client says:
* BYE Internal error occurred. Refer to server log for more information.
The session looks like

(interestingly the tshark output strips out the user name and password which is
convenient but which may mean there's not enough
information?)
I rolled back to 2.0.17 and it was fine again.
It's the same config files for both, same maildirs etc etc. All I did was
change the dovecot version from 2.0.17 to 2.1rc5
However I see from the changelog that 2.1rc5 added a default namespace inbox:
diff doveconf-n.2.0.17 doveconf-n.2.1-rc5
1c1
< # 2.0.17 (684381041dc4+): /etc/dovecot/dovecot.conf

> special_use = \Sent
> }
> mailbox "Sent Messages" {
> special_use = \Sent
> }
> mailbox Trash {
> special_use = \Trash
> }
> prefix > }
We had this section commented out in 2.0.x so there was no namespace inbox
anywhere.
