Docker-mailserver: How to block all emails from specific domain or particular email address?

[x-Felix]

I read through readme.md and wiki - Email filtering w/ Sieve. But not really find the answer I need.

What I want to achieve is quite basic, just block emails from particular sending address or domain.
Such as block all email from @abuse.com, or [email protected]. Matched emails can be rejected or discarded.

Is there easy way to put unwanted domains into a postfix config file at server level or I have to use Sieve email filtering?

Thanks.

I will mark this appropriately (and as wontfix, since this is a question not actually regarding _docker-mailserver_), but to be honest, this issue tracker is not designed to answer this kind of question, since https://www.google.com should be sufficient:)

• Use Postfix smtpd_recipient_restrictions (https://github.com/tomav/docker-mailserver/wiki/Setup-docker-mailserver-using-the-script-setup.sh#email)
  Add to config/postfix-send-access.cf
  [email protected] REJECT

• Use Spamassassin (https://github.com/tomav/docker-mailserver/wiki/FAQ-and-Tips#how-can-i-manage-my-custom-spamassassin-rules)
  Add to config/spamassassin-rules.cf:
  blacklist_from [email protected]

• Use Sieve (https://github.com/tomav/docker-mailserver/wiki/Configure-Sieve-filters)
  Add to config/[email protected]:

require ["fileinto", "reject"];

if address :contains ["From"] "[email protected]" {
   fileinto "INBOX.spam";
} else {
     keep;
}

Could you please add the solution to the wiki?
