Well, I tried setting the following in /etc/environment and restarting the server: DOVECOT_HOSTDOMAIN="mail.domain.test" After doing so, I verified that the command "dovecot --hostdomain" returned "mail.domain.test" and not "appserver4.domain.com"; however, the email received header still shows: Received: from mail.domain.test by appserver4.domain.com (Dovecot) with LMTP id .... I also tried adding the following line to /etc/dovecot/conf.d/10-master.conf and restarting the dovecot service: hostname = mail.domain.test doveconf shows that "hostname = mail.domain.test", and now the received headers show: Received: from mail.domain.test by mail.domain.test (Dovecot) with LMTP id .... So it seems that "hostname" is a valid, respected Dovecot directive. --- Scott On Tue, Aug 23, 2016 at 4:58 AM Sami Ketola <sami.ketola at dovecot.fi> wrote:> Hi, > > Looking at the source code it seems that the fqdn used in the lmtp > received headers is > fetched from environment variable DOVECOT_HOSTDOMAIN and if that is not > defined > gethostbyname() is used. > > You can try setting that prior launching dovecot. > > Sami > > > > On 19 Aug 2016, at 21:43, Scott W.

Edgar, /etc/hostname has "appserver4". I'm using this server for more than just a postfix+Dovecot server, so don't want to name it "mail.domain.test". In any case, I already solved the issue I was having by adding "hostname mail.domain.test" to /etc/dovecot/10-master.conf and reloading the configuration. Easy-peasy, just doesn't appear to be well documented. --- Scott On Tue, Aug 23, 2016 at 7:35 PM Edgar Pettijohn <edgar at pettijohn-web.com> wrote:> I'm chiming in kind of late, but what's in /etc/hostname? > > Sent from my iPhone > > > On Aug 23, 2016, at 6:03 PM, Scott W.
