Misleading error message "Mailbox has an invalid format"

[Sebastian Hagedorn]

Hi,

we are running 2.1.16. Today it took me some time to find out what was 
going on when the following happened:

[cyrus at lvr1 imap]$ quota -f
user.a3103129: Mailbox has an invalid format

Initially I naturally believed this message and tried to reconstruct the 
mailbox. Only after some lengthy  experiments did I find the real cause:

[cyrus at lvr1 a3103129]$ ll /var/lib/imap/quota/B/user.a3103129
-rw-------    1 cyrus    mail            8 Apr 22 14:47 
/var/lib/imap/quota/B/user.a3103129
[cyrus at lvr1 a3103129]$ cat /var/lib/imap/quota/B/user.a3103129
3082446
[cyrus at lvr1 a3103129]$ mv  /var/lib/imap/quota/B/user.a3103129 /tmp
[cyrus at lvr1 a3103129]$ quota -f
user.a3103129: quota root user.a3103129 --> (none)

So: it's not the mailbox that has an invalid format, it's the quota file ...

Cheers, Sebastian Hagedorn
