 `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.

 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.
