There are several possible causes.
An attempt to send a test E-mail notification fails with the following error message:
Mail server error
There are several possible reasons:
- A Firewall or your provider blocks the outgoing SMTP connection;
- The connection is lost while sending an E-mail;
- Not all of the E-mail settings were entered correctly
- Make sure all the E-mail settings are correct and up-to-date.
Examples of settings for some email servers:
- Make sure your Firewall does not block your outgoing network connections via the selected SMTP server port. Make sure your Firewall does not block the TrueImage.exe process;
- Check that your network provider does not block your outgoing network connections via the selected port. You can use telnet to check this. See Using telnet to Test Open Ports;
- Check if your e-mail provider offers alternative SMTP servers or different ports. If yes, try using these alternative settings;
- Check your network connection and network access to the SMTP server. For example, do this with the ping command:
- Open Start menu, type cmd and press Enter to open Command Prompt
- In Command prompt, type ping <SMTP server address> and press Enter;
- Check if there are any errors reaching SMTP server
This error can also occur if your computer's name contains special symbols such as _ & #. Change computer name and remove these symbols to solve the issue.
