I have been running my a smtp server on plan9 for about 10 years but I beleive I am having more and more incomming mail bounce because of plan9's lack of support for tls 1.2.
What is anyone else doing about this? stop ovvering ESMTP in smptd? Using a 3rd party smtpd supplier (google?) Does 9front support tls1.2 now? use facebook instead of email (joke). Other... -Steve (hoping replies don't bounce)
