No. $sender is lexically scoped and has no meaning outside the loop.
The error is with the code. If you look at
the docs, the Close() method sends the mail, if you move $sender->Close() outside the loop, the best you can hope for is only one email being sent - the last one.
I can understand why you think that the problem is with the module's code - the error messages look that way - because the module uses
warn() and not
carp() in those lines.
