Change password on Postfix+Gmail relay setup
As root go to /etc/postfix. Open main.cf. Find the line smtp_sasl_password_maps to get the name of the file currently used. Open that file and edit the password in it to the right of the ":" after the login/mail address. Create a hash db file of the file: sudo postmap /etc/postfix/name-of-file-without-db-at-the-end Restart postfix, service postfix restart. Check /var/spool/deferred for any mail that was unable to be sent and the /var/spool/defer for the reasons.
