You might encounter an error when trying to connect to the Hornetsecurity smart host for outgoing emails. You might experience the following errors:
Connection to 184.108.40.206:25 timed out
(The shown IP address might change from connection to connection.)
If you encounter this error, check the restrictions set for your firewall. This issue might be due to strict restrictions on the firewall, preventing a connection on port 25. To prevent this from happening in the future, make sure to adjust the firewall settings to allow the complete Hornetsecurity IP-range to be accessed via port 25. You can find the IP range from our onboarding website.
Authentication error (SASL/SMTP)
You might encounter authentication errors if your password contains special characters like explanation mark or winged brackets. Double check if any of those specials characters are in use and remove them from your current password and try again.
