Currently mailcow is used in the Email Node by default in your Private Cyberspace (assuming you are an average home user).
Your application integrator should have your Email Node set up with usable defaults, so you should NOT need to touch it unless you are not satisfy with the result.
The following are some DNSBLs available in your Private Cyberspace:
- bl.spamcop.net ^
- combined.abuse.ch ^
- dnsbl.sorbs.net ^
- multi.surbl.org ^
- zen.spamhaus.org ^
^ turned on by default
Some open source servers that can be added to the Mail Node to complement mailcow.
1. Web Mail
2. Encrypted Synchronisation
