imap4...

I've noticed that if I do a login using the $login value:


my $login = "imap4://$username:$password\@$server/";
my $f = $mgr->open($login,
		   authenticate => 'PLAIN',
		   folder => 'bogofilter'
		   );
print $f->name,"\n";
print scalar $f->messages,"\n";
OUTPUT
	/
	0

my $folder = $mgr->open(type => 'imap4',
			server_name => $server,
			username => $username,
			password => $password,
			authenticate => 'PLAIN',
			folder => 'Inbox'
			);

print $folder->name,"\n";
print scalar $folder->messages,"\n";
OUTPUT
	Inbox
	1500

$folder = $mgr->open(type => 'imap4',
		     server_name => $server,
		     username => $username,
		     password => $password,
		     authenticate => 'PLAIN',
		     authenticate => 'PLAIN',
		     folder=>'bogofilter.hamnew');

print $folder->name,"\n";
print scalar $folder->messages,"\n";
OUTPUT
	bogofilter.hamnew
	5

I'm not very sure where this might be.  But my guess is in the sub 
transporter of IMAP4.pm

Then using a $login string of imap://username... the folder is not taken 
when you specify is as 'folder => ' and if you append the folder to the 
end of the $login, you fail to log in.
