-## Managing users and aliases
-
-### Users
-
-As you've seen above, users are managed in `config/postfix-accounts.cf`.
-Just add the full email address and its encrypted password separated by a pipe.
-
-Example:
-
-    user1@domain.tld|{CRAM-MD5}mypassword-cram-md5-encrypted
-    user2@otherdomain.tld|{CRAM-MD5}myotherpassword-cram-md5-encrypted
-
-To generate the password you could run for example the following:
-
-    docker run --rm \
-      -e MAIL_USER=user1@domain.tld \
-      -ti tvial/docker-mailserver:v2 \
-      /bin/sh -c 'echo "$MAIL_USER|$(doveadm pw -s CRAM-MD5 -u $MAIL_USER )"'
-
-You will be asked for a password. Just copy all the output string in the file `config/postfix-accounts.cf`.
-
-    The `doveadm pw` command let you choose between several encryption schemes for the password.
-    Use doveadm pw -l to get a list of the currently supported encryption schemes.
-
-### Aliases
-
-Please first read [Postfix documentation on virtual aliases](http://www.postfix.org/VIRTUAL_README.html#virtual_alias).
-
-Aliases are managed in `config/postfix-virtual.cf`.
-An alias is a full email address that will be:
-* delivered to an existing account in `config/postfix-accounts.cf`
-* redirected to one or more other email addresses
-
-Alias and target are space separated.
-
-Example:
-
-    # Alias to existing account
-    alias1@domain.tld user1@domain.tld
-
-    # Forward to external email address
-    alias2@domain.tld external@gmail.com
