Note that the error you see comes from sqwebmail/maildir.c:

       if (dbobj_open(&tmpdb, save_tmpdbname, "N")) {
               syslog(LOG_ERR, "Can't create cache file |%s|: %s\n", save_tmpdbname, strerror(errno));
                error("Can't create cache file.");
       }

This in turn calls either bdbobj_open or gdbmobj_open [see dbobj.h].

So my guess is that the difference between your home and work machines is
something to do with the version of bdb and/or gdbm installed, or which one
it has decided to use (see dbobj.config and config.log)

But apart from that, have you checked you're not out of disk space or inodes
(df -i), and you don't have a filesystem quota for the 'vpopmail' user?
Although I'd expect a different error message than 'No such file or
directory' for those problems, it could be that bdbobj_open / gdbmobj_open
is setting errno to something else.

What if you do:

  su - vpopmail
  cd /home/vpopmail/domains/xxxxxx.com/stefan.onken/Maildir
  echo "hello world" > tmp/foobar
  cat /etc/passwd >> tmp/foobar
  cat tmp/foobar

Is that successful?

Do you get a new zero-byte file each time you try to login, and the same
error message?
