IOERROR: opening quota file: File name too long

[Gary Mills]

We're running cyrus-imapd-2.3.8 on Solaris 10.  Recently, the `quota'
command failed with this error in syslog:

    Jun 29 19:58:49 castor quota[27067]: [ID 240394 local6.error] IOERROR: opening quota file /imap/conf/quota/N/user._______.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.INBOX.Deleted Messages: File name too long

Running it by hand resulted in this error:

    # /usr/local/cyrus/bin/quota > /var/tmp/1.quota
    failed building quota list for '*': System I/O error: %m

The deeply-nested folder seems to be created by Apple Mail.  I could
delete it with `cyradm', but the user kept recreating it.  Is there a
fix for this problem, perhaps in later Cyrus versions?  We use the
`quota' command to generate over-quota warnings automatically.
