Having not tested this but just eyeballed the code, I'm fairly sure
you're adding a logic error here, or is $smtp_encryption guaranteed to
be defined at this point?

I will admit to being ignorant of much of Perl's semantics, but I had
assumed that the line prior to my additions addresses this:

$smtp_encryption = '' unless (defined $smtp_encryption);

You're right, I just misread the diff. Nevermind.
