I changed vexim acl into:
deny    message       = DNSBL listed at $dnslist_domain\n$dnslist_text
          dnslists      = zen.spamhaus.org


and got this

550 relay not permitted
LOG: H=mx.spamcops.de (spamcops.de) [87.106.79.226] F=<> rejected RCPT
listme@???: relay not permitted

So basically now I am no longer an open relay?

My only question would be how do I make sure that even if someone is in
spamhouse, they can send mail if they authenticate?


Thanks!
