How to redirect Mail sender and receiver based?

Question

Hi there, 
 
 I need to redirect mails based on sender and receiver domain. How can I realize this? Is an additional Outbound policy the right way to do this? Based on "@senderdomain.com" and receiverdomain "@*.de-mail.de" in need to send the mail to different gatways (DE-Mail Provider Mailserver) 
 
 Thx for help

There are several ways to accomplish this. However the "right" way for you depends on the criteria you wish to match against. 
 Your options are: 
 via IP address 
 via Envelope Sender 
 via DATA sender 
 or a combination of all 3. 
 
 Example 1: 
 DATA sender 
 Data control / add / inbound 
 rule type: messages matching specific words or phrases 
 check off: enable advanced 
 rule config: regular expression enter: .* / add 
 message attributes : add / header / 
 Name: From 
 is exact match: jimmy.bob@mydomain.com 
 main action / select redirect message to another server. 
 
 envelop sender: 
 use a watch list rule additional policy. 
 under the select users tab: click custom group 
 use : **@mydomain.com 
 
 for an IP based rule use the first example and rather than a header rule.. select IP .. then is or is not. 
 
 other tricks may include adding the host to internal mail relays.. for example if you have a web server at 170.23.1.2 and you want to relay mail from the external web server, to the internet.. configure the server to relay to the SEA .. then add that ip as an internal mail host and the appliance would consider it internal > external .. 
 as for external > internal.. create an entry for the domain under ,ail delivery servers and associate it to the mail domain .. this will allow you to route mail anywhere you wish. 
 
 any of these options should work by themselves, or in combination .. have fun
