Sorry that i'm new to this maillist, and i'm not sure i understand the
posting policy. Sorry for the direct reply. Is it the right way to send
email back to the list with Forward and send to receiver
"[email protected]" ?

In my server config, i used courier-imap's pop3d and imapd for client to
check email from Outlook and Webmail. To narrow down, i found that both
check email method produce these dead file. (i.e. pop3d and imapd also
produce this error )

Maybe my "delete" word is misleading. The "delete" i said is the action in
webmail, where actually is moving the email from Inbox to Trash, but not
really delete the mail file.

I cannot reproduce the error myself. because i cannot read these dead file.
So, maybe special character within the mail file cause the error? i dunno.
And i can't find a way to figure it out. My server mainly user is Chinese,
with charset zh-TW and zh-CN. There're lots of email with chinese title and
content. And i guess courier-imap should handle locale quite well.

My server have about 200 virtual domain and around 1500 mail account. About
1 dead file produced within few days, in different virtual domain and
different user ( i.e. different folder in filesystem ).

As i found that all these dead file exist in "cur" mail folder, and only
imap will move the mail file to these folder (with both pop3d and imapd),
this is the reason i think that courier-imap have problem with my existing
filesystem.

I used fedora core 2 disk with default server installation for a new
harddisk partitioning and formatting in ext3. And run up2date to update all
packages.

My existing kernel is 2.6.5-1.358. I know that i should update to the newest
kernel. However, i cannot reboot the server for kernel upgrade now because
these dead email file will certainly make the bootup filesystem check fail
and the worse case is corrupt that partition. I guess that somebody else
should use this default FC2 kernel as well with no filesystem related
problem. I searched the ChangeLog in FC2 between this old kernel and most
updated kernel and no such filesystem related bug fixes. (maybe i was wrong)

I'm not trying to say that i rejected the possibility for the source of
problem from this kernel. I'd like to know if someone tell me that "yes,
this kernel version is buggy and will produce corrupted file at ext3
filesystem in some manner", so i can simply format this server, update
kernel, re-install anything and done. But seems that the problem is not that
exact. I know that i should try to upgrade kernel version, but are there any
possible solution besides this? I think that this is my last last step if i
really can't find solution.

For these dead email file, i cannot find any I/O related error in syslog.
And I'm quite certain that this is not a hardware failure.

Again, thx for anyone reading this and i hope that i can solve this problem
asap.
