The problem seems to be a misconfiguration of Exim.
My Astaro currently has three eth ports: lan, dmz and wan.
The local mail server mail.acme.com (final destination for acme.com) is on DMZ and WAN eth port is configured with an alias of public mail server IP.
Each time a mail is sent to ***@acme.com I get something like:
1JPxS8-0002Ks-6w
Contrary to what Exim thinks, remote address is not the local host, just an IP alias of an ethernet port.
How can I solve this issue?
Thank you.
Luigi
