incomplete error message in exception when SSL fails

[jazzkutya]

|| 151 if ($self->_security eq 'starttls') { || 152 $self->_throw("can't STARTTLS: " . $smtp->message) || 153 unless $smtp->starttls(%{ $self->ssl_options }); || 154 }

You forgot to include $@ in the message of the exception. $@ contains vital information on the problem whose absence makes me curse everyone involved in email stuff. PR later

Stuck in the same problem, got message:

After halfday of googling, checkong and reverse engineering, found true problem

SSL connect attempt failed error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

Which was in $@ after $smtp->starttls but masked with $self->_throw

Looks like the easiest way to fix it is to include $@ into message.
