What if the message SIZE announcement is missing (not sent by google), if TLS is turned off? You'll get exactly this behavior.

Thank you Thomas not just for the write up, but for taking all the time necessary to figure all this out 2) IO::Socket::SSL and Net::SSLeay Both of mine are the latest versions (newer than the recommended / minimum that shows in the info gui) 3) A different / additional problem with TLS? Can we tell what algorithm Google uses? So we wasted allot of time looking for a TLS/SSL issue - life is not easy. ******************************* Back to the 'TLS' relation. Forget it - this issue has totaly nothing to do with TLS/SSL! ******************************* What you describe elsewhere makes sense, BUT looking at my tests, an email with 11 MB of attachments takes 19 seconds with TLS turned off, and with TLS on 662 seconds. That's 34 times longer. I know SSL takes processing power, but that's a huge overhead no? *Can we tell from the logs / debug / or some other test what TLS algorithm google is using*? Since I only see this horrific slowdown with Google and TLS, I wonder if I might only allow a (slightly?) lesser algorithm that's still secure but not quite as intensive. Note that identical hardware runs Apache on Windows with OpenSSL, Exchange (SSL), and others without any noticeable slowdown due to the encryption. You've clearly identified a major different problem with grow, etc, but I'm not so sure that I'm not also experiencing a SSL/TLS problem. Eagerly awaiting the next version!
