Hi everyone ! Courier mailserver (a couple of boxes in use) allows me to accept mail for a domain, but not deliver it locally (acceptmailfor). This will allow for spam/viruschecking before the mail gets transfered to another server (exchange in my case). Is it possible to solve this from the IspConfig interface ? I did read a post about relaying, but that's not exactly the same, right? The Ispconfig box is not used for sending mails. The MX record must point to the Ispconfig box, which should then accept, check and transfer the mails of this one domain (not all!) to the exchange server - who's ip should not be in the mx record. In my case the nameserver of IspConfig is not used - yet CU Peter
