in thread SMTP "auth" problem after upgrade

Apart from the fact that $smtp is scoped out of existence and Noauth being tested for defined looks like a tautology in this snippet, I would be inclined to factorise out the "unless" in such a situation where most of the lines of code in the two branches are identical, and use a tertiary operator instead :
my $smtp = MIME::Lite->send('smtp', $host, defined( $something_else ) ? AuthUser => $user, AuthPass => $pass : Noauth => 1, Debug => 1 );

One world, one people
