Hi Guys,
We are using an external spamfilter machine to keep spam away from our hosting (DA) machines. That works for 90% of the spam, but some spammers send mail directly to the hosting server instead of the spamfilter server. I think that they just do an hostname lookup on the domain, not on the MX record.
What I want to do is blocking all mail that not come from the spamfilter machine. I would like to be able to configure this per domain.
Does anybody know how to configure that in Exim? Ofcourse I can pay for it when it has to be a custom solution.
Thanks!
