>250-AUTH GSSAPI If you have THIS, then at least the hard part of configuring postfix is done. Some things to check: - There should be some kind of log message from postfix with hopefully a useful error (I do not know where postfix logs its errors, but probably somewhere in /var/log). - A lot of daemons fork and exit, that's why the process ID from postfix shown in systemd does not exist. You should be able to find the actual process id with 'ps'. - A common problem is that the keytab does not have the correct permissions; a lot of time the keytab is owned by root and I suspect postfix is running as 'postfix' or some other non-root user. If this is the problem the error message logged should be relatively self- explanatory. --Ken ------------------------------------------ Cyrus: SASL Permalink: https://cyrus.topicbox.com/groups/sasl/T1e24816c0d686c81-M8d3f71111caf467c479eee39 Delivery options: https://cyrus.topicbox.com/groups/sasl/subscription
