I have my Yunohost server running on a RaspberryPi at Home. The mail server works great … but I got this message from an email I sent today:
550-Your message was rejected by this system and was not delivered.
550-Reason: This system will not accept messages from servers/devices with
no reverse DNS. IP=[1**.***.***.***] 550-Protection provided by: MagicMail

Is there a way of getting around this?
