autodiscover.xml

Provides IMAP/SMTP Autodiscover capabilities on Microsoft Outlook/Apple Mail, Autoconfig capabilities for Thunderbird, and Configuration Profiles for iOS/Apple Mail.

Deploy

Microsoft Outlook/Apple Mail

URL (POST XML): https://{{app_domain}}/Autodiscover/Autodiscover.xml

Create a SRV DNS Record:

Service Protocol Value, Destination, Target Port Priority Weight TTL
_autodiscover _tcp {{app_domain}} 443 5 0 3600

Test your Autodiscover configuration (Microsoft Outlook): https://testconnectivity.microsoft.com (Click on "Outlook Autodiscover")

Mozilla Thunderbird

URL (GET): https://{{app_domain}}/mail/config-v1.1.xml

Create a CNAME DNS Record:

Name, Host, Alias Value, Destination TTL
autoconfig {{app_domain}} 3600

iOS / Apple Mail

URL (GET): https://{{app_domain}}/email.mobileconfig?email=EMAIL_ADDRESS

Redirect users to above URL and the MobileConfig Profile will be downloaded. The user will be instructed to install the profile to configure their email.

Notes

The above autoconfiguration methods assume the following:

  • Username: {{email}} (Entire email address)
  • Encryption: SSL/TLS

Workarounds

I only have one mail server with both IMAP and SMTP on the same machine (mail.mydomain.com).

Create CNAME DNS Records that alias imap/smtp to your machine, like so:

Name, Host, Alias Value, Destination TTL
imap mail.mydomain.com 3600
smtp mail.mydomain.com 3600

My settings are different or not compatible with these settings.
