Maildrop : unable to change to home directory

eliufoo · 07-18-2008, 07:27 AM

hi guys,

I've been working on this ( /usr/bin/maildrop: Unable to change to home directory)error the for past 5 days with no luck. I've the following setting setup, (Virtual Users With Postfix, PostfixAdmin, Courier, Mailscanner, ClamAV On CentOS).

I have also notice that, courier is not creating maildir, even when postfixadmin is sending a default welcome email. The email get stuck in mailq.

Please ASSIST,

here are my configuration details:

postconf -n

try this in /etc/maildroprc

Code:

#SHELL="/bin/sh"
VERBOSE=5

# commands and variables for making the mail directories
maildirmake=/usr/lib/courier-imap/bin/maildirmake
mkdir=/bin/mkdir
rmdir=/bin/rmdir
MAILDIR=$DEFAULT

# make the user's mail directory if it doesn't exist
`test -e $MAILDIR`
if ($RETURNCODE != 0)
{
 `$mkdir -p $MAILDIR`
 `$rmdir $MAILDIR`
 `$maildirmake $MAILDIR`
}

# make the .Junk folder if it doesn't exist
JUNK_FOLDER=.Junk
_JUNK_DEST=$MAILDIR/$JUNK_FOLDER/
`test -d $_JUNK_DEST`
if ($RETURNCODE != 0 )
{
 `$maildirmake $_JUNK_DEST`
 #auto subscribe. the following works for courier-imap
 `echo INBOX.Junk >> $MAILDIR/courierimapsubscribed`
}

if (/^X-Spam-Flag:.*YES/)
{
    exception {
        to $DEFAULT/.Junk/
    }
}

That will automatically create the mail directories if they don't exist, and will also put anything marked as spam by SA in the .Junk mail folder for that user.

hi BlueC,

I'm still facing the same problem. I tried the following

maildrop -V 3 -d ally@example.co.tz maildrop

Quote:

maildrop: authlib: groupid=1001
maildrop: authlib: userid=1001
maildrop: authlib: logname=ally@example.co.tz, home=/var/vmail2, mail=/var/vmail2/ally@example.co.tz/
maildrop: Changing to /var/vmail2
maildrop: Unable to change to home directory.

What other methods can I use to investigate and resolve this problem?

Thanks,

BlueC · 07-18-2008, 10:28 AM

I dunno, does /var/vmail2 exist? Does it have the right permissions?

eliufoo · 07-18-2008, 10:55 AM

It does exist and have all the right permissions.

Are you available now to help with my issue on a IM?

BlueC · 07-18-2008, 11:10 AM

Nope. What is the maildir field in your mysql database?

eliufoo · 07-18-2008, 11:51 AM

it maildir

values inside the fields appear as ally@example.co.tz/

eliufoo · 07-23-2008, 11:10 AM

I got this resolved. I take my permission post back.

I change the permission from /var/vmail from 600 (recommend by the tutorial i was using) to 700. i.e

chmod 700 /var/vmail
chown vmail:vmail

Quote:

drwx------ 9 vmail vmail 4096 Jul 23 12:45 vmail

I'm also running the maildroprc script from BlueC

One more thing. I'm using Postfixadmin v2.2.x and it not creating maildir files like it supposed too. My maildir structure looks like /var/vmail/user@domain.tld instead of /var/vmail/domain.tld/user/

Does any one have a solution for this?

Yes, in config.inc.php from postfixadmin set the following variables as follows:

Code:

$CONF['domain_path'] = 'NO';
$CONF['domain_in_mailbox'] = 'YES';

That should do it.
