Simple selfhosted throw-away email
GoSpam supports various configuration options. All options with their respective defaults are listed below.
The configuration file is a yaml file and can be located in the current directory (gospam.conf) in etc (/etc/gospam/gospam.conf) or
in the users home directory ($HOME/.gospam/gospam.conf).
SMTPListenAddress: ":25"
HTTPListenAddress: ":80"
Domain: "localhost"
AcceptedDomains:
- "spam4.jonaskoeritz.de"
- "localhost"
AcceptSubdomains: false
MaxStoredMessages: 100000
RetentionHours: 4
CleanupPeriod: 5
MaximumMessageSize: 5242880
SMTPTimeout: 60
MaxRecipients: 10
RandomAliasPlaceholder: false
AcceptedDomains can be omitted to accept any recipient domain, this will make the server look like an open relay.
To add persistence to the service you can optionally supply connection details for a Redis server:
RedisBackend:
Address: "127.0.0.1:6379"
Password: ""
DB: 0
The MaxStoredMessages does not apply to the redis backend. Additionally searching for aliases using * and ? placeholders
is available only when using the redis backend.
Just run the gospam binary.
You have to create DNS records to configure the machine running GoSpam as the mail server for any domain or subdomain.
The web interface can be configured to listen on a specific interface only (e. g. 127.0.0.1:80 to listen on localhost)
this makes it possible to make the SMTP listener publicly accessible and keep the web interface private.
