Hi,
Our mailbox.db file recently became corrputed, and so I wrote a little
script to generate a new one, based purely on the contents of
/var/spool/imap/ . The script worked fine, and I could see all the
folders in cyradm, and could log in as a user with no problem. However,
my import seems to have lost all directory permissions, and as such, I
could not do either a folder list of see emails when logged in as an
IMAP user (though I was fine as a POP3 user with seeing emails). When I
manually added permissions for the user for each folder, I regained the
ability to see emails and folders.
Can anybody tell me what I did wrong?
What I did:
#!/usr/bin/perl
listdirs("user");
sub listdirs ($) {
my $dir = shift;
my @dirs = ();
opendir DIR, "/var/spool/imap/$dir";
while ($entry = readdir DIR) {
next if ($entry =~ /^\./ || ! -d
"/var/spool/imap/$dir/$entry");
$cyrname = $dir;
$cyrname =~ s:/:.:g ;
if ($dir eq "user") {
$username = $entry;
} else {
$username = $dir;
$username =~ s:^user/([^/]+).*:$1: ;
}
print
"${cyrname}.${entry}\tdefault\t$username\tlrswipcda\n";
# print "sam ${cyrname}.${entry} $username lrswipcda\n";
push @dirs, $entry;
}
closedir DIR;
foreach (@dirs) { listdirs("$dir/$_") ; }
}
the hashed out line has the command I pasted into cyradm to fix the
permissions problem.
This generates a file with entries like this:
user.robin default robin lrswipcda
user.robin.Abuse default robin lrswipcda
user.robin.Clients default robin lrswipcda
user.robin.Sent_Mail default robin lrswipcda
(the white space is all tabs) I then used this as the import source for
the new database (after firast deleting the old one and all files in db)
cat /var/imap/mailboxes.db.import | /usr/cyrus/bin/ctl_mboxlist -u
I also noticed there were one or two folders with white space in their
names, and that cyradm complained about this. Does anyone know how to
get it to accept these?
I had to do something similar last night. I don't know how much
downtime we would have had when doing a full reconstruct but now our
downtime was only 14 hours (We have nearly 800GiB of email). Luckily it
was in the weekend and most of it at evening and night hours.
To answer your question: put single quotes around the mailbox. E.g.:
sam 'user.login.folder name' login lrswipcda
I also wrote a script that made the login.sub files. In our setup these
where flat files.
