Mail::Sender (as well as most email modules) allows you to use a name with the email address in brackets. You aren't faking an address so don't use fake_from.

my %mail;
$mail{'to'} = $emails;
$mail{'file'} = 'test.txt';
$mail{'subject'} = 'test';
$mail{'msg'} = "Please work";

my $sender = new Mail::Sender{
   smpt=> 'mailhost',
   from=> 'Joe Shmoe <joe@pleasework.com>',
};
$sender-> MailFile(\%mail);
