Autodiscover (Outlook) and Autoconfig (Thunderbird)

Recent NetManager builds support account auto-configuration for Outlook and Thunderbirds (and any other mail clients that support either of these mechanisms). Examples of this in operation can be found here: Thunderbird and Outlook


  • You should already have a DNS A record for your mail server (e.g.
  • You should have SSL certificates in place and your webserver should be accessible from the outside world, i.e. and should work
  • You may need to set up a spoofed internal DNS record so that the external name (e.g. points to your internal IP address (depending on your firewalling)
  • You will probably want enable SMTP authentication for many of your users as auto-configured accounts will have this feature enabled

DNS changes required

To enable this to work, you will need to set up two DNS CNAME records for your external domain name(s):

  • autodiscover should be a CNAME to your mail server's external name (e.g.
  • autoconfig should be a CNAME to your mail server's external name (e.g.
  • Ideally, you should also create a SRV record for _autodiscover._tcp for port 443, e.g.
    _autodiscover._tcp      IN      SRV     1 10 443


To test Thunderbird autoconfig go to:

You should see an XML file beginning with:
<clientConfig version="1.1">
<emailProvider id="netmanager">

Outlook autodiscover is harder to test as it requires you to send it XML (and SRV records cannot be tested in a web-browser either). However you should be able to visit the following (which will report No email address given):
