Error: TLS not available due to local problem
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.

Re: Error: TLS not available due to local problem
Any ideas? Thanks in advance. Look at logs. Out: 450 4.1.8 adyybiwut2...@ne.jp: Sender address rejected: Domain not looks like DNS problem Not also that you can tune postfix log level to debug out this kind of problem. -- Eero

Vegard Svanberg: 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). Look in your LOGFILE. Postfix does not reveal the details of this problem to the SMTP client. http://www.postfix.org/DEBUG_README.html#logging Wietse
