Warning
Rspamd service needs to be enabled for the reply anonymously feature to work.
See #169 for more details.

Docker compose is the recommended way to run this image. You can use the following docker compose template, then run the container:
docker compose up -d
docker compose logs -f
docker compose pull
docker compose up -d
If you want to use the artisan command to perform common server operations like manage users, passwords and more, type:
docker compose exec addy anonaddy <command>
For example to list all available commands:
docker compose exec addy anonaddy list
docker compose exec addy anonaddy anonaddy:create-user "username" "[email protected]"
docker compose run --entrypoint '' addy gen-dkim
generating private and storing in data/dkim/example.com.private
generating DNS TXT record with public key and storing it in data/dkim/example.com.txt
default._domainkey IN TXT ( "v=DKIM1; k=rsa; "
"p=***"
"***"
) ;
The keypair will be available in /data/dkim
.
If you don't have an existing GPG key, you can generate a new GPG key with the following command:
docker compose exec --user anonaddy addy gpg --full-gen-key
Keys will be stored in /data/.gnupg
folder.
You can define additional environment variables that will be used by the app
by creating a file named .env
in /data
.
In some cases you may want to override the default Postfix main configuration
to fit your infrastructure. To do so, you can create a file named
postfix-main.alt.cf
in /data
and it will be used instead of the generated
configuration. Use at your own risk.
Warning
Container has to be restarted to propagate changes
If a public DNS resolver is used, it may be blocked by Spamhaus and return a 'non-existent domain' (NXDOMAIN), and soon will start to return an error code:
Aug 3 10:15:40 mail01 postfix/smtpd[23645]: NOQUEUE: reject: RCPT from sender.example.com[xx.xx.xx.xx]: 554 5.7.1 Service unavailable;
