Hi,
Some of my user are getting mail at their spam box from some
domain. Can you suggest what can be done to prevent mail getting
delivered at spam box? They prefer to get it in inbox.

Angus,
Did you think about simply using port 25, no authentication
or encryption, which is how squirrelmail on QMT used to be
configured, relying on HTTPS alone for password and email
security across the cloud as the email (after the cloud) is
submitted directly to the server (tcpserver) by the server
(apache) itself (127.0.0.1) rendering encryption useless or
redundant. I think this is the route I will go because with
every upgrade of roundcube, the webmail I prefer, there seems
to be issues with past configurations.

The certificate is installed.
The hostname in '/etc/hosts' resolves, and responds to pings.
I replaced the self-signed PEM that shipped with qmailtoaster with
one
that I made myself by concatenating the ‘.key’ and ‘.crt’ files
from my
server certificate. Inspecting the resulting .pem with ‘openssl
x509 -in
servercert.pem -text’ confirms that the resulting .pem is for the
domain
that I expect. File permissions and ownership are correct.
'/etc/hosts' for my newly-built server contains the following line:
127.0.1.1s6.mydomain.com <http://s6.mydomain.com> s6
(obviously, 'mydomain' is not the actual name here). The .pem file
contains the lines:
Subject: OU=Domain Control Validated, OU=PositiveSSL,
CN=mail.mydomain.dev <http://mail.mydomain.dev>
and
X509v3 Subject Alternative Name:
DNS:mail.mydomain.dev <http://mail.mydomain.dev>,
DNS:www.mail.mydomain.dev <http://www.mail.mydomain.dev>
's6.mydomain.com <http://s6.mydomain.com>' and'mail.mydomain.dev
<http://mail.mydomain.dev>' all resolve to the same IP.
My existing qmailtoaster server (running an older version of the
software) has '/etc/hosts' containing:
127.0.1.1s2.mydomain.com <http://s2.mydomain.com> s2
and the .pem file contains:
Subject: OU=Domain Control Validated, OU=PositiveSSL
Multi-Domain,
CN=mydomain.com <http://mydomain.com>
and
X509v3 Subject Alternative Name:
DNS:mydomain.com <http://mydomain.com>, DNS:mail.mydomain.com
<http://mail.mydomain.com>, DNS:www.mydomain.com <http://www.mydomain.com>
's6.mydomain.com <http://s6.mydomain.com>' resolves to the same IP
as'mail.mydomain.dev <http://mail.mydomain.dev>';
's2.mydomain.com <http://s2.mydomain.com>' resolves to the same IP
as'mail.mydomain.com <http://mail.mydomain.com>'.
As far as I can see, the two situations are equivalent, with the
slight
difference that the official server name of the new box
('s6.mydomain.com <http://s6.mydomain.com>') is not a subdomain of
the domain in the PEM file
('mail.mydomain.dev <http://mail.mydomain.dev>'), whereas on the
old box the name of the host
('s2.mydomain.com <http://s2.mydomain.com>') is a subdomain of one
of the domain names in the PEM
file ('mydomain.com <http://mydomain.com>'). I don't know if this
is a possible cause of my
problems.
One other difference is that I don’t have a PTR record for
's6.mydomain.com <http://s6.mydomain.com>'. An RDNS lookup on the IP
of's2.mydomain.com <http://s2.mydomain.com>' will
yield 's2.mydomain.com <http://s2.mydomain.com>', but an RDNS
lookup on the IP of
's6.mydomain.com <http://s6.mydomain.com>' yields the FQDN of the
Linode VM it runs on. Could
that be an issue?
I'll keep digging on this, but if anyone has any suggestions of
tests or
tools I might use, I'd welcome your recommendations.
Thanks,
Angus

Following Eric's instructions, I edited '/etc/roundcubemail/config.inc.php' so that
it contains:
