That is not a requirement. Providing a completent implementation of a stub resolver, ANSI C, POSIX, etc., is a requirement. Wietse

Perhaps you've replaced the OpenSSL or other shared libraries that scache was compiled against, and the ABI changed. >postfix/master: warning: /usr/lib/postfix/sbin/scache: bad command > startup -- throttling >postfix/smtp: warning: problem talking to service private/scache: > Connection timed out >postfix/smtp: warning: problem talking to service private/scache: > Connection timed out >postfix/smtp: warning: disabling connection caching > as the last line says, connection caching was disabled. This is not a problem, but a good defensive measure to keep going. > Is this permanently, or until next restart of thew master process? Neither, because master(8) will eventually unthrottle the service, but it would likely crash again, so sort of permanently, because unthrottling won't help. You have a broken system, or a very unusual one, which managed to find a bug in scache(8) that nobody else is running into. -- Viktor.

Also, if your Postfix is out of date, there are probably other things too. Who knows, maybe even an update that fixes the unrelated thing that went wrong. Scott K

If I send one email to multiple email addresses on same domain, will this trigger scache? (ie, deliver multiple emails in one connection to the server?) Did you build Postfix? Is this one of those container-optimized libc implementations? no, I am using standard postfix package (3.4.14) on Debian 10 I don't suspect anything wrong with the build, I think something unrelated on my system might have been wrong. I have restarted the server, and I thought I would trigger scache, to make sure it is working now

warning: disabling connection caching
Hello, I had this in my logs: postfix/master: warning: process /usr/lib/postfix/sbin/scache pid 1215 killed by signal 11 postfix/master: warning: /usr/lib/postfix/sbin/scache: bad command startup -- throttling postfix/smtp: warning: problem talking to service private/scache: Connection timed out postfix/smtp: warning: problem talking to service private/scache: Connection timed out postfix/smtp: warning: disabling connection caching as the last line says, connection caching was disabled. Is this permanently, or until next restart of thew master process? Also, if I wanted to test scache, how can I trigger it? If I send one email to multiple email addresses on same domain, will this trigger scache? (ie, deliver multiple emails in one connection to the server?) thank you
