This article describes which SRV records should be created for a domain. These SRV records allow clients to automatically detect which host and port should be used for relevant domain services.
SRV records (known as Service Location Records) are used by clients to automatically configure the host and port for messaging services when an account is created. These records are created within the advertised DNS zone for a domain.
Whilst Microsoft clients typically use an autodiscovery service to detect mail client settings, many clients (particularly iOS/OSX and mobile clients) will use DNS to locate a user's messaging service settings.
The following table lists typical SRV records that should be created for a domain to improve the experience when user's create e-mail accounts:
|_caldav||CalDAV Calendaring Support|
|_caldavs||CalDAV Calendaring Support over SSL|
|_carddav||CardDAV Address Book Support|
|_carddavs||CardDAV Address Book Support over SSL|
|_imap||IMAP Mail Access Support|
|_imaps||IMAP Mail Access Support over SSL|
|_pop3||POP3 Mail Access Support|
|_pop3s||POP3 Mail Access Support over SSL|
|_submission||SMTP Client Mail Transfer Support|
|_autodiscover||Specifies the server and port responsible for providing autodiscovery for mail services (via MailEnable's Autodiscovery Service)|
These DNS records typically appear within a domains DNS Zone as: [SRV]._tcp.example.com.
The process for configuring these records depends on which vendor is providing DNS for the domain. It can only be done by a person who has administrative access to the DNS service responsible for the domain.
As an example, to create a DNS SRV record for IMAP using Microsoft's DNS, you should do the following:
