Hi,

Some days ago, I have used the maildir-size-fix.pl script (cited in this mail thread: http://www.dovecot.org/list/dovecot/2013-January/087942.html, in available here: http://dovecot.org/tools/maildir-size-fix.pl).

This is a very good script and helped me a lot!

However, some compressed mails where misdetected as non-compressed mail. So I discovered that some versions of the file command (some old versions) can wrongly detect gzipped files as being Minix filesystems.

Actually, the error was occurring in about 1 gzipped mail for each 60000 or 100000 mails.

I reported this file command bug here: https://bugs.launchpad.net/ubuntu/+source/file/+bug/1646233.

But I think it's worth to make a small improvement in maildir-size-fix.pl, making it more error prone. What do you, guys, think about this?

This is the patch I'm proposing:

``` --- maildir-size-fix.pl.orig 2016-12-01 14:41:30.044689101 -0200 +++ maildir-size-fix.pl 2016-12-01 14:49:42.971197715 -0200 @@ -37,7 +37,10 @@

```

Added, thanks!
