Autodiscovery
=============
`RFC6186 <https://www.rfc-editor.org/rfc/rfc6186>`_ allows supporting email clients to automatically discover SMTP / IMAP addresses
of the mailserver. For that, the following records are required:
================ ==== ==== ======== ====== ==== =================
Record TTL Type Priority Weight Port Value
================ ==== ==== ======== ====== ==== =================
_submission._tcp 3600 SRV 5 0 587 mail.example.com.
_imap._tcp 3600 SRV 5 0 143 mail.example.com.
_imaps._tcp 3600 SRV 5 0 993 mail.example.com.
================ ==== ==== ======== ====== ==== =================
Please note that only a few MUAs currently implement this. For vendor-specific
discovery mechanisms `automx <https://github.com/rseichter/automx2>`_ can be used instead.
