I haven't yet tried actually prefixing another component, but I did make some changes (acer is the test subject, axis is the smarthost). Did you mean: 127.0.1.1 test.acer.corp test or 127.0.1.1 test.acer.corp acer ? I'm a bit mystified at the moment, so here's what I did. I edited mailname and hosts, adding the "1"s, reconfigured exim (making no changes to the dialog boxes), and rebooted. $ cat /etc/mailname acer.corp1 $ cat /etc/hosts 127.0.0.1 localhost 127.0.1.1 acer1.corp acer1 192.168.1.14 axis.corp axis # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters $ hostname acer $ domainname (none) $ dnsdomainname dnsdomainname: Name or service not known $ mail.mailutils -s acer1.corp1 auser@axis Cc: acer1 in hosts, corp1 in mailname $ and here's the email on axis: >From au...@acer.corp Thu Apr 28 11:37:06 2022 Return-path: <au...@acer.corp> Envelope-to: auser@axis Delivery-date: Thu, 28 Apr 2022 11:37:06 -0500 Received: from [192.168.1.10] (helo=acer) by axis.corp with esmtp (Exim 4.92) (envelope-from <au...@acer.corp>) id 1nk78c-0001yL-Bm for auser@axis; Thu, 28 Apr 2022 11:37:06 -0500 Received: from auser by acer with local (Exim 4.94.2) (envelope-from <auser@acer>) id 1nk78b-0000HX-6v for auser@axis; Thu, 28 Apr 2022 11:37:05 -0500 Subject: acer1.corp1 To: auser@axis X-Mailer: mail (GNU Mailutils 3.10) Message-Id: <E1nk78b-0000HX-6v@acer> From: me <au...@acer.corp> Date: Thu, 28 Apr 2022 11:37:05 -0500 acer1 in hosts, corp1 in mailname ^D and the logs from each: 2022-04-28 11:37:05 1nk78b-0000HX-6v <= auser@acer U=auser P=local S=370 2022-04-28 11:37:06 1nk78b-0000HX-6v => auser@axis R=smarthost T=remote_smtp_smarthost H=192.168.1.14 [192.168.1.14] K C="250- 387 byte chunk, total 387\\n250 OK id=1nk78c-0001yL-Bm" 2022-04-28 11:37:06 1nk78b-0000HX-6v Completed 2022-04-28 11:37:06 1nk78c-0001yL-Bm <= au...@acer.corp H=(acer) [192.168.1.10] P=esmtp K S=559 id=E1nk78b-0000HX-6v@acer 2022-04-28 11:37:06 1nk78c-0001yL-Bm => auser <auser@axis> R=local_user T=mail_spool 2022-04-28 11:37:06 1nk78c-0001yL-Bm Completed So, for the hostname, /etc/hostname (acer, untouched) or DHCP (I'm not sure if my router would send that, though it does know acer's name) seems to be winning. Cheers, David.
