From the error messages I would think the error is not in the code you posted, but instead on the module Mail::Sender.

Update 1: - next paragraph proven wrong, and I decided I don't like Mail::Sender :)

Try moving the new Mail::Sender and $sender->Close outside the loop and see if that fixes it, or look inside Mail::Sender for clues.

Update 2: - message "Mail was sent OK." is premature. (and let me in the wrong path)

On a side note, you line reading could be done with one regex instead of two and a split: 
my ($email, $file) = $_ =~ /^'(.*)','(.*)'$/;

or something to that effect
