Hi list, I'm receiving several thousand errors per day from Postfix. The error is "454 4.7.0 TLS not available due to local problem" (see below).
TLS is working, and has been for a long time. I've verified this by telnet and running STARTTLS. But it seems to stop working from time to time, and I suspect it happens when the server has a lot to do (read: being flooded by spam). I set tls_random_source to dev:/dev/urandom to rule out any entropy-related problems, but no go. The error messages give me nothing to go on, and the mail logs don't give any clues either. This is Postfix 2.5.5-1.1 (from Debian Lenny) on x86-64.
