Autodiscover settings

Microsoft no longer supports autodiscover for SMTP / IMAP in recent versions of Outlook, so this guide is no longer supported.

What is Autodiscover and what is it used for?

Autodiscover is a protocol that allows email clients (e.g. Thunderbird, Apple Mail, Microsoft Outlook) to configure server connection parameters for your email address automatically, instead of configuring all parameters manually. This will save yourself some time, especially if you have to configure a lot of accounts.

To use the autodiscover system, make sure that your client supports this feature, as not all email clients currently support it. Furthermore, it is necessary to change the DNS configuration of your domain to add some parameters that will allow you to contact the autodiscover service in an appropriate way.

Configuring Autodiscover for your domain certainly makes it easier for users the first set up their email account, and voids any found typos. It is also a very simple configuration to perform and has no additional cost or impact on performance.

The implementation of Qboxmail Autordiscover provides IMAP and SMTP parameters for desktop email clients and Microsoft® Exchange ActiveSync for Smartphones.

The Microsoft® Exchange ActiveSync service is available for domains with Enterprise plan only.

The advantage of using EAS is its easy configuration on mobile devices and the real-time Push notifications for new emails and events in the calendar.


Not all email clients are currently compatible. A list of clients that can host Autodiscover is available below:

Client Version Protocol
Microsoft Outlook 2013 and newer IMAP and SMTP
Microsoft App Mail Contacts and Calendar Windows 10 Microsoft® Exchange ActiveSync
Mozilla Thunderbird 60 and newer IMAP e SMTP
Android latest Microsoft® Exchange ActiveSync
Apple iOS 12 and newer Microsoft® Exchange ActiveSync

Setup Autodiscover through VirtualHost

To guarantee a full compatibility with the majority of email clients, we suggest to create your own VirtualHost associated to your domain, in the form autodiscover.mycompany.com with a valid SSL certificate installed. In VirtualHost, you will have to add a 302 redirect to Qboxmail's Autodiscover server.

Substitute **mycompany.com** with the name of your domain.

You can find a VirtualHost example with the redirect rules in the example below:

<VirtualHost *:443>
  ServerName autodiscover.mycompany.com
  ServerAlias autoconfig.mycompany.com

  RewriteEngine on
  RewriteRule ^.*config-v1\.1\.xml$ https://autodiscover.qboxmail.com/thunderbird.php [NC,R=302,L]
  RewriteRule ^.*autodiscover\.xml$ https://autodiscover.qboxmail.com/outlook.php [NC,R=302,L]
  RewriteRule ^.*autodiscover\.json$ https://autodiscover.qboxmail.com/outlook.json.php [NC,R=302,L]

  SSLEngine on
  SSLCertificateFile /path/to/ssl.cert
  SSLCertificateKeyFile /path/to/ssl.key

Alternatively, if you cannot change the virtualhost directly, you can create a .htaccess file to insert in the document root of your autodiscover.mycompany.com domain:

RewriteEngine On
RewriteRule ^.*config-v1\.1\.xml$ https://autodiscover.qboxmail.com/thunderbird.php [NC,R=302,L]
RewriteRule ^.*autodiscover\.xml$ https://autodiscover.qboxmail.com/outlook.php [NC,R=302,L]
RewriteRule ^.*autodiscover\.json$ https://autodiscover.qboxmail.com/outlook.json.php [NC,R=302,L]
Both configurations showed above require a **mod_rewrite** module enabled in Apache.

Setup Autodiscover through DNS Record

If you do not have the possibility to create a Virtual Host in HTTPS, you can still configure the Autodiscover through a configuration on the DNS domain. It is important to remember that this configuration may not be enough to make the autodiscover compatible on your email client. Access the DNS management panel of your domain's provider and add the following CNAME record as follows:

Record Record type Value
autoconfig.mycompany.com CNAME autodiscover.qboxmail.com.
autodiscover.mycompany.com CNAME autodiscover.qboxmail.com.

The above setting authorizes your email client to contact the Qboxmail autodiscover service to obtain the mail server configuration data for your domain.

The autoconfig record is used by Thunderbird, while autodiscover is used by EAS / Outlook.

Once the above listed records have been added, it can take up to 24 hours for the DNS change to become fully operational.

Setup autodiscover with White Label

Resellers have access to DNS White Label records to set up in their customers' domains. Using White Label records, every direct reference to Qboxmail on the Webmail inteface will be removed. To download the PDF related to White Label, access your client area and follow the link: White Label Parameters (login required).

The White Label configuration is included in your service fee.

Setup autodiscover in Private Label

Customers who activated the Private Label service will find out that the Qboxmail implementation providers the POP, IMAP, and SMTP parameters directly to its users. However, it will be necessary that hostnames linked to the domain with active Private Label be in one of the following forms:

  • pop.DOMAIN
  • imap.DOMAIN
  • smtp.DOMAIN

Verify the correct setup of the autodiscover records

In order to verify the correct settings for the autodiscover records on your domain, you can run the following nslookup commands from a terminal:

nslookup -q=cname autoconfig.mycompany.com nslookup -q=cname autodiscover.mycompany.com

which should respond respectively with the following result:

autoconfig.mycompany.com canonical name = autodiscover.qboxmail.com. autoconfig.mycompany.com canonical name = autodiscover.qboxmail.com.
