Is there a fix for the "451 4.3.0 Error: queue file write error" yet? I heard to increase the smtp_proxy_timeout = 600s in the main.cf file, but then I heard that can run down your server.
Is there any patches or hot fixes that actually work? I have Postfix 9.3.0 and the 451 error is still not fixed. Shawn Fee SGF IT Solutions, LLC | IT Manager 813.817.8706 <mailto:s...@sgfitsolutions.com> s...@sgfitsolutions.com
