In general my postfix mail server is working well, it is receiving emails with optional STARTTLS. But I am occasionally seeing an error message like this in the log:
2016-12-11 00:32:19 dl1 postfix/smtpd[13665]: SSL_accept error from unknown[14.215.156.100]: lost connection The connection giving rise to the error is never from one of our machines/users. Should I be worried about it? Does it indicate some bad configuration on my side? Dominic
