UTF7 mailbox codification error

[Manel Gimeno Zaragozá]

Hello,

As I been explaining in the thread "Problem recover replica" that I'm trying to use Mail::IMAPTalk perl module to fetch some data. I've write this new thread because I get an error when I try to execute the following code:
...
...
...
my $IMAPs1 = Mail::IMAPTalk->new(
        Server => $master,
        Port => 143,
        Username => $username,
        Password => $password,
        Uid => 1,
);

my $IMAPs2 = Mail::IMAPTalk->new(
        Server => $slave,
        Port => 143,
        Username => $username,
        Password => $password,
        Uid => 1,
);

$IMAPs1->set_unicode_folders(1);
$IMAPs2->set_unicode_folders(1);

sub Get_Fetch(){
  $IMAPs1->select("$_[0]") || die "IMAP error: $@";
  $IMAPs2->select("$_[0]") || die "IMAP error: $@";

  my $s1sha1 = $IMAPs1->fetch('1:*', 'digest.sha1')  || die "IMAP error: $@";
  my $s2sha1 = $IMAPs2->fetch('1:*', 'digest.sha1') || die "IMAP error: $@";

  my $exit_sha1 = &compare($s1sha1,$s2sha1,"sha1");
  if ($exit_sha1 eq 1){
        &print_result($s1sha1,$s2sha1);
        print "ERROR: sha1 buzon $_[0]\n";
        return $exit_sha1;
  }
}
...
...
...

I get the following error:
Uncaught exception from user code:
        IMAP error: Select failed for folder 'user.dataaper.Comunicaci&APM-n Interna' : IMAP Command : 'select' failed. Response was : no - Mailbox does not exist at ./test.pl line 105, <$_[...]>   line 5.
 at ./test.pl line 105
        main::Get_Fetch('user.dataaper.Comunicaci&APM-n Interna') called at ./test.pl line 86

The problem is when I try to select the "bold folder" I get that it does not exist, but I it does! I've capture the traffic with tcpflow and I see the following:
...
...
192.168.066.093.46078-192.168.066.092.00143: 34 select "user.dataaper.Comunicaci&-APM-n Interna"

192.168.066.092.00143-192.168.066.093.46078: * OK [CLOSED] Ok
34 NO Mailbox does not exist
...
...

As you can see the method "select" sends a wrong "folder" "user.dataaper.Comunicaci&-APM-n Interna". It puts a "-" after "&" and because of that it fails!

If I comment the lines "set_unicode_folders", I get the following error:
Please report to rjlov at /usr/local/share/perl5/Mail/IMAPTalk.pm line 3859, <$_[...]> line 5.
Warning only: IMAPTalk not using unicode_folders at /usr/local/share/perl5/Mail/IMAPTalk.pm line 3860

Please report to rjlov at /usr/local/share/perl5/Mail/IMAPTalk.pm line 3861, <$_[...]> line 5.

I've try to comment the part of the code on IMAPTalk.pm that make the codification conversion, and it works ok if "set_unicode_folfer" lines are not present. But I'm not sure If i can get worst problems in the future about that.
...
...
#  if ( $Self->unicode_folders()
#    && ( $FolderName =~ m{[^\x00-\x25\x27-\x7f]} ) )
#  {
#    $FolderName = Encode::encode( 'IMAP-UTF-7', $FolderName );
#  }

#  if (! $Self->unicode_folders() ) {
#    warn("Please report to rjlov");
#    Carp::cluck("Warning only: IMAPTalk not using unicode_folders");
#    warn("Please report to rjlov");
#  }
...
...
#  if ( $Self->unicode_folders()
#    && ( $FolderName =~ m{&} ) )
#  {
#    $FolderName = Encode::decode( 'IMAP-UTF-7', $FolderName );
#  }

#  if (! $Self->unicode_folders() ) {
#   warn("Please report to rjlov");
#    Carp::cluck("Warning only: IMAPTalk not using unicode_folders");
#    warn("Please report to rjlov");
#  }


How can I avoid this error? Or force that the method do not "convert" the strings.

Thanks & Regards.
