Raspberry Pi 3 Model B
i doubt it is a bug probably more a problem in (my) configuration.
dashboard is working and pi is working but i do get an enormous amount of error lines in syslog because of cayenne trying to sent a message via email. the message is sent every minute and each time it is rejected by the mailserver. this fills up my syslog. the message tries to tell me that myDevices is running. the problem is that the to address is not resolved for some reason. very well possible that this is not an cayenne issue but all other mail messages work so somehow cayenne uses another way to sent the message? below the message as in the syslog with the rejection:
250 2.1.0 Sender OK
250 2.1.5 Recipient OK
354 Start mail input; end with .

i am not really familiair with linux so have no idea where to look.
i can see two solutions:
- disable sending the message (it has no use for me i do not need it) but where would i do that can’t find where it is sent.
- solve the alias so make “root” in the to field a valid address but i do not know where to do that. i use ssmtp and root is on that level replaced by email@example.com as can be seen in the beginning of the message but at one place at least that doesn’t happen. any help in where to look would be appreciated.
sorry if it is obvious as i wrote i am not very experienced with linux and thanks for any help.
