Policy outbound mail

Question

Hi to all,
W've encountered some problems making a policy based on outbound mail (especially with rewriting the Envelope Sender and message splintering). See the description below:
conditions:
- The recipient is a specific domain;
- The sender is a member of a specific LDAP group
actions:
- Rewrite the Envelope Sender, From header and Reply-To header into another domain;
- Relay the message to a specific SMTP gateway.
Does anybody have a hint/solution for the problems above?
Kind regards,
Ben Hoorn

Hi,
Rewriting the headers like you require would usually involve 'masquerading' which can be done a couple of different ways, and is explained in a lengthy article here: http://tinyurl.com/qpjj2
I would encourage you to read the article to determine which is the best method for you; this would heavily depend on the amount of users you need to masquerade for...
From there, you can create an outgoing mail policy with 'Senders' consisting of either a list of addresses, or and LDAP group query, and 'Recipients' containing a list of addresses, or entire domains.
