No, this is wrong from a security standpoint, although it works since 
you're ignoring the cert data.  You'll be vulnerable to a MITM attack. 
You should instead take the advice of the second half of brian's blog 
post and tell LWP::UserAgent about your root CA or install the root CA 
into your operating system's list of trusted CAs (which means you don't 
have to patch rt-mailgate).
