If you've configured (the DNS of) our VPS mail service and configured your mail software (manually) and your mail is not sent, there'll most likely by a problem with the configuration.

To investigate the cause of the problem, consult the log files of your VPS. For Postfix this can be done with the command:

tail -f /var/log/maillog

For Exim use the command:

tail -f /var/log/exim_mainlog

Please note that some control panels may use different locations for the log files. In that case, check the file location using the commands:

ls /var/log
ls /var/log/exim
ls /var/log/postfix
