DNSBL on port 25 only
Does anyone know how to configure Exim4 on Vesta so that it only checks IPs against DNSBLs when the connection is to port 25?
The problem is that many users use SMTP from all sorts of addresses that could end up on DNSBLs, especially domestic ADSL IPs, and I want to configure Exim to stop all spam coming in on port 25, and configure 465 and 587 to require authentication and avoid being blacklisted. I'm sure there's a way to do it with ACLs, but I've not figured out how best to do it with Vesta configurations.
Ideas?
