[Dovecot] Maildir++ implementation issues.

[Apps Lists]

Hi Timo and crew!

I'm doing more testing with Dovecot and Maildrop today and have run across
some strangeness.

It appears as if Maildrop stores updates to the maildirquota file in a way
that causes Dovecot to ignore them.

In my test scenario, Dovecot just rebuilt my maildirsize file to the
following:

0S
86213796 108

After delivering a few messages through Postfix -> Maildrop and have the
following maildirsize file:

0S
86213796 108
        5102            1
      387708            1
        5093            1
      382406            1
        3550            1
      268337            1

Note the pretty formatting.  These are spaces.

Unfortunately, Dovecot seems to ignore these when reading the maildirsize
file in maildirsize_parse().  It appears to be using sscanf to look for
numeric entries:

                if (sscanf(*lines, "%lld %d", &bytes_diff, &count_diff) != 2)


I've read and re-read the maildir++ specification at
http://www.inter7.com/courierimap/README.maildirquota.html and can't
understand why Maildrop implements things this way.
