.. _`1368`: https://github.com/Mailu/Mailu/issues/1368
My emails are getting defered, what can I do?
`````````````````````````````````````````````
Emails are asynchronous and it's not abnormal for them to be defered sometimes. That being said, Mailu enforces secure connections where possible using DANE and MTA-STS, both of which have the potential to delay indefinitely delivery if something is misconfigured.
If delivery to a specific domain fails because their DANE records are invalid or their TLS configuration inadequate (expired certificate, ...), you can assist delivery by downgrading the security level for that domain by creating an override at ``overrides/postfix/tls_policy.map`` as follow:
.. code-block:: bash
domain.example.com may
domain.example.org encrypt
The syntax and options are as described in `postfix's documentation`_. Re-creating the smtp container will be required for changes to take effect.
