SMTP Authentication |
Top Previous Next |
Gibraltar can be used as SMTP server for sending mails. This can be very useful for external workers that do not have the possibility to reach their outgoing mail server. To use Gibraltar they need account information (username and password) which must be created in the module User.
Only authorized users are allowed to use the Gibraltar firewall as mail relay.
ATTENTION: Don't forget to create a filter rule, that allows external users to access to the port 25 (SMTP port) from outside. Activate this filter rule only after checking that the SMTP authentication is running. Otherwise Gibraltar acts as "Open Relay" and allows every sender to send emails.
