Hello everyone, I would like to setup iRedMail as SMTP proxy in front of Ms Exhcnage and use it as a spam-filtering solution temporary.  Regarding this topic http://www.iredmail.org/forum/topic8559 … ilter.html
I've already changed the above parameter $forward_method in the amavis config file (/etc/amavisd/amavis.config) to point to the internal address of my Exchange CAS server and changed the MX records to point to my iRedMail box, but every time I send email to excising user of my domain the error is: Recipient address rejected: User unknown in virtual mailbox table. How can I skip the user verification parameter or what else can I do in order to bypass this error - probably an ldap query to check users?
Do I have also to create transport_maps in postfix config to forward emails to Exchange?

Thank you in advance.

Regards,

Plamen
