Look in Postfix logs. https://www.postfix.org/DEBUG_README.html#logging Look for obvious signs of trouble Postfix logs all failed and successful deliveries to a logfile. When Postfix uses syslog logging (the default), the file is usually called /var/log/maillog, /var/log/mail, or something similar; the exact pathname is configured in a file called /etc/syslog.conf, /etc/rsyslog.conf, or something similar. When Postfix uses its own logging system (see MAILLOG_README), the location of the logfile is configured with the Postfix maillog_file parameter. When Postfix does not receive or deliver mail, the first order of business is to look for errors that prevent Postfix from working properly: % grep -E '(warning|error|fatal|panic):' /some/log/file | more Note: the most important message is near the BEGINNING of the output. Error messages that come later are less useful. The nature of each problem is indicated as follows: * "panic" indicates a problem in the software itself that only a programmer can fix. Postfix cannot proceed until this is fixed. * "fatal" is the result of missing files, incorrect permissions, incorrect configuration file settings that you can fix. Postfix cannot proceed until this is fixed. * "error" reports an error condition. For safety reasons, a Postfix process will terminate when more than 13 of these happen. * "warning" indicates a non-fatal error. These are problems that you may not be able to fix (such as a broken DNS server elsewhere on the network) but may also indicate local configuration errors that could become a problem later. _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
