I've been scratching my head over this one. The answer seemed like it would be simple, but I encountered a few exceptions.

First, I noticed that you were using TLS, so I tried it with Net::SMTP::TLS. The problem there for me was that the module requires Net::SSLeay, but that's broken and won't work for me.

Second, all the servers that I use basically use the two mechanisms, DIGEST-MD5 and CRAM-MD5, so LOGIN wasn't available and even PLAIN wasn't always available.

Third, wondering why the LOGIN mechanism seemed to be awol somewhere, I figured that this stuation was a "gotcha". See the internet draft The LOGIN SASL Mechanism for more details.
