A simple solution may be to read the domainlist local_domains =
from a flat file that needs to hold the names of the user defined domains. On 14.02.2018 10:28, Cyborg via Exim-users wrote:

If someone will add domain 'gmail.com' exim will treat it as local domain. The only way is to check MX.There is no easy solution to the problem. Local domains defines those domains, the server shall receive email for. You could add a rule to the check_rcpt acl , to see, if IN MX of the domain points to your server. It's doable, but could be tricked also. Way easier is to blacklist domains, you will never serve emails for like gmail.com. domainlist local_domains = @ : localhost : localhost.localdomain : ${lookup mysql { SELECT domainname FROM .. WHERE ... AND DOMAIN NOT IN ( "gmail.com","t-online.de","gmx.de","gmx.net","outlook.com" .... ) }} You could also build an sql with a db defined blacklist, which would be easier to maintain. Hope that helped, Marius
