Ok, especially for you I did create a user for testing the issue and it
appears this way:
1) created testuser and therefor /var/spool/mail/testuser was not there
2) date | sendmail -t realuser@mailhost.tld testuser
means I sent the new testuser a mail with the actual data as body
mail received and was written into /var/spool/mail/testuser as the first
mail, nothing else was in that file
3) telnet mailhost.tld 25
user testuser
pass secret
list --> shows 1 new mail
retr 1 --> printed out the mail with full header and body
dele 1 --> deleted the mail
quit
4) checking /var/spool/mail/testuser showed then the new mail deleted
BUT the dummy message in it:
From MAILER-DAEMON Fri Apr 23 01:21:04 2004
Date: 23 Apr 2004 01:21:04 +0200
From: Mail System Internal Data <MAILER-DAEMON@mailhost.tld>
Subject: DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA
Message-ID: <1082676064@mailhost.tld>
X-IMAP: 1082676046 0000000001
Status: RO
This text is part of the internal format of your mail folder, and is not
a real message. It is created automatically by the mail system
software.
If deleted, important folder data will be lost, and it will be
re-created
with the data reset to initial values.
So though there is the X-IMAP header tag in it not IMAP daemon had
participated. The ipop3 is writing it in. So your first question is
answered, the one from the follow-up mail too.
What do you mean with mail disappearing? As I understand what you might
see is that the mailserver gets confused when you take him the inbox
mail file away. Nothing I wonder about. Use a standard conform method to
get new mails from one host to another. Either use fetchmail on the host
which shall receive the mail. Or use an /etc/aliases entry if you wish
the mail getting on one host to be sent to a different one. That is the
function of aliases file.
Ok, your last question, an important one. Be sure the permissions are
really
$ ls -ld /var/spool/mail /var/spool/mail/tuser
drwxrwxr-x 3 root mail 4096 23. Apr 01:20 /var/spool/mail
-rw-rw---- 1 tuser mail 542 23. Apr 01:21 /var/spool/mail/tuser
Check whether they got changed running mailbox access. Maybe a different
user uses a tool which modifies the permissions? I am running uw-imapd
an have a user with KMail as her MUA and never faced such maillog
messages. The message
Mailbox Vulnerable - Directory /var/spool/mail must have 1777 protection
only appears when the file /var/spool/mail/$user is set writable by
accounts different than the user itself and systemuser mail. Or maybe
even the permissions on the user's inbox are chmod 600 (like to be seen
from the bugzilla article i pointed to before:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=120196). On my FC1
I have uw-imap RPM version imap-2002d-3 installed.
