Anything is possible. :-)

Exim is supposed to follow the rules that are described in
http://www.inter7.com/courierimap/README.maildirquota.html
No locking is involved. When creating a new maildirsize file, the data
is written to a temporary file which is then renamed. When adding a
single line to an existing file, the logic is
(void)lseek(fd, 0, SEEK_END);
(void)write(fd, buffer, len);
The file is opened with O_RDWR. Hmm. I wonder if it should be
O_RDWR+O_APPEND instead?
