Change dovecot hostname
I have noticed that the name of my private server running dovecot appears in email headers rather than the public-friendly name of my server.
Is there a method to specify an alternate server name for the dovecot server to use for itself in the dovecot configuration files? I performed a few Google searches and was not able to find the answer to my question.
user@server1:~$ dovecot --version 2.2.9 user@server1:~$ dovecot -n # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.16.0-77-generic x86_64 Ubuntu 14.04.4 LTS ext4 auth_mechanisms = plain login info_log_path = /var/log/dovecot.log log_path = /var/log/dovecot.log mail_location = maildir:/var/mail/vhosts/%d/%n namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = scheme=PLAIN username_format=%u /etc/dovecot/dovecot-users driver = passwd-file } protocols = " imap lmtp pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } service imap-login { inet_listener imaps { port = 993 ssl = yes } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl = required ssl_cert = </etc/ssl/certs/server1_combined.pem ssl_key = </etc/ssl/private/server1_key.pem userdb { args = uid=vmail gid=vmail home=/var/mail/vhosts/%d/%n driver = static }
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.

I'll check out the environment variable method, but I also ran "doveconf | grep hostname" and it returned "hostname = ". This leads me to believe it might be possible to specify a hostname directive in one of Dovecot's configuration files. The problem is 1) I'm not sure that it is truly possible to specify the Dovecot hostname in a configuration file and 2) I'm not sure which configuration file and section it should be placed in.

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.

I'm chiming in kind of late, but what's in /etc/hostname?

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.
