Hello again,

http://www.iredmail.org/wiki/index.php? … nal.Script

This page explains how to configure an LDAP user account to redirect to an external script.  Is there any way to get this functionality with an Active Directory backend?  Right now, it seems as though once you go AD, there is no support for any other functionality (like local users, /etc/postfix/alias contents, etc)

A variation on this question goes like this: right now, my old mail server (with local users and /etc/alias), I could set up aliases to external addresses, like so:

Is there any way to achieve this same functionality with an Active Directory backend?

I do have iRedAdmin Pro LDAP, but I suspect that it is not going to be too helpful when it comes to AD integration.

Thanks again!
