Are you bored with all tried, but still cannot send email successful?
Please follow steps from below link which help to test how AutoPass server interacts with SMTP server, so if similar error or behavior of email not being sent is obtained, then analyze, configure and collect logs for each table listed scenario for last 3 settings for the config.properties file, documenting what happens with each testing.
Note: if a combination/configuration used, works for customer on this tool, configure same on AutoPass server's file mentioned on step 3 above
Hope it is helpful.
