Managing connection options
The page is used to configure connection settings, such as limiting the number of simultaneous connections per IP address and enabling real-time blacklist checking or reverse DNS verification.
The following settings can be configured on the page Connection Control:
- Configuring simultaneous connections
- Using a real-time blacklist
- Using reverse DNS verification
- Using the reputation service
- Delaying the SMTP greeting
- Enabling the SMTP VRFY command
- Enabling SMTP authentication for email hybrid service
- Changing the SMTP port
- Using access lists
To collect and view detailed information about some connections, allow connection control functions to save these details in the mail processing log, accessed via an appliance. When the function is activated, the log collects detailed data regardless of whether the connection control itself is enabled. This function is available for the following connection control options:
- Real-time blacklist (RBL)
- Reverse DNS lookup
- Reputation service
- SMTP greeting delay
