'mas-smtp' Configuration

enaio® mail-archive-service 11.0

Configuration parameters of the massmtp-prod.yml file.

The 'mas-smtp' service is not obligatory for plain mailbox archiving.

A customizable configuration file is available to download, which you can use as a basis for the configuration.

Parameter	Type	Description	For example	Default
mas-smtp.port	Number	Port where SMTP waits for incoming messages. It can be set to any value between 1024 and 65535.

PowerShell example: `netsh interface portproxy add v4tov4 listenport=25 listenaddress=0.0.0.0 connectport=25000 connectaddress=127.0.0.1`	25000	25000

Encryption of Configuration Values

The configuration values in the massmtp-prod.yml file located in the \config\ directory of enaio® service-manager can be encrypted:

Open the command prompt as the administrator and change to the \service-manager\tools\encryption\ directory.
Run the following command: encode.bat "value" -W.

The encrypted value is displayed in round brackets with 'ENC' before it: ENC(encryptedvalue).
Copy the encrypted value with the leading 'ENC' and with the round brackets and enter it into the configuration file.
Save the configuration and restart the service, if necessary.

If the value to be encrypted contains quotation marks or ends with a backslash, these characters must be preceded by the backslash.
Example: encode.bat "passwordwith\"quotation\"marks" -W

IP Filters

IP filters can be set up, both for access to services and for access to management endpoints, in order to access individual or even all services.

Configurations for individual services have priority over configurations for all services via the application-prod.yml configuration file.
