I'm using maildrop as a transport in postfix to handle virtual mailboxes. When I inject a message to go to one of these virtual mailboxes, I get the following error in the maillog:

(temporary failure. Command output: /usr/bin/maildrop: Invalid home directory
permissions - world writable. )

I haven't been able to find an answer to how to fix this error, just more people asking the same question. I tried looking through the maildrop source code and found this in main.C:

if ( stat(".", &buf) < 0 || !S_ISDIR(buf.st_mode) || buf.st_mode & S_IWOTH || buf.st_uid != getuid()) { errexit=EX_TEMPFAIL; throw "Invalid home directory permissions - world writable."; }

I was going through some .h files trying to figure out what S_ISDIR and S_IWOTH meant. But I figured asking here would be faster.

What permissions should the /home/vmail directory and the virtual mailbox directories inside of that be? Right now I have the following:

/home/vmail vmail:vmail (dr-xr-xr-x) /home/vmail/slugbug.org vmail:vmail (dr-xr-xr-x) /home/vmail/slugbug.org/testing mark:mark (dr-xr-xr-x) /home/vmail/slugbug.org/testing/.mailfilter mark:mark (-r--------) /home/vmail/slugbug.org/testing/Maildir mark:mark (drwxr-xr-x)

I've also tried making the slugbug.org directory owned by mark:mark.
