Hello, First of all, thanks mouss for the reply.
I have made few steps forward in my hub and spoke setup. I set up the hub which is forwarding mail to the agencies' server based on a MySQL table. The problem is located on agencies' servers. As I first said, I have only 1 domain. When I want to send a mail to a user from the other site (and same domain), I get this error: "Recipient address rejected: User unknown in virtual mailbox table". Indeed, the 2 agencies' servers are setup to be the final destination for the same domain. I tried the "relay_recipient_maps" directive with no success. Could someone help me please? Let me know if you need more accurate details. Best regards. -- *************************** Jonathan Amiez Administrateur système j...@edatis.com it-pa...@edatis.com ad...@edatis.com *************************** Le samedi 26 juin 2010 00:01:27, mouss a écrit : > Jonathan Amiez a écrit : > > Hello everyone. > > > > I'm trying to set up a specific mail server configuration on 3 sites. > > The first one is hosting a mailhub (with spam filter, etc.) and the > > 2 others are agencies. > > The 2 agencies use the same domain (eg. edatis.com) for mailing. > > I'm currently working on the first agency's server. > > Accounts are stored in MySQL db replicated on the 2 sites from the hub. > > > > So, my problem is : if I don't care about "transport" statements, all > > mail is delivered on the local agency server, and if I do, mail is > > directly sent to the other agency, without passing by the mailhub. > > I need all outgoing email (remote agency or internet) to pass by the hub. > > > > I found very few inaccurate info about this setup (seems kind of unusual) > > so I'm asking for help.
