Newbie maillog errors

[Tom Plancon]

Hello,

I've sort of inherited managing a cyrus 2.2.12 email server with postfix
on a FC4 linux box. Generally things run smoothly, but I'm still getting
up to speed and I see some errors regularly appearing in the maillog.
The two most frequent are:

Dec 13 13:16:41 pelican imap[6609]: SQUAT failed to open index file
Dec 13 13:16:41 pelican imap[6609]: SQUAT failed

And

Dec 13 13:18:14 pelican lmtpunix[6857]: IOERROR: fstating sieve script
/var/lib/imap/sieve/x/xuser/defaultbc: No such file or directory

The last error is reported for all imap users at various times. I know
the imap partition is set as  /home/imap, which I understand is not the
default install location. Any light anyone can shed on what the errors
mean and if I should take steps to correct is appreciated.

Thanks!
