Limiting by ip is not very convenient in this case, so I'd rather block by
usernames or domains.

I'm not sure what other part of the configuration you would need to see. I
can paste the complete exim.conf if that would help.

begin authenticators

fixed_plain:
driver = plaintext
public_name = PLAIN
server_prompts = :
server_condition = "${perl{checkuserpass}{$1}{$2}{$3}}"
server_set_id = $2

fixed_login:
driver = plaintext
public_name = LOGIN
server_prompts = "Username:: : Password::"
server_condition = "${perl{checkuserpass}{$1}{$2}}"
server_set_id = $1
