I have never been able to send texts to my phone via email from a remote computer that is running an observatory. It is using the same Earthlink SMTP server I use on my home computer, and it works from home. Main difference I can see is that the message from the observatory are just a few words like “roof open”, being sent by a program so their is not a subject, body etc.
The computer sending these uses my email address as the “from”, so when they fail I get an email that says:
----- The following addresses had permanent fatal errors ----- >
(reason: 550 permanent failure for one or more recipients rejecting banned content))
----- Transcript of session follows ----- ... while talking to d79033a.ess.barracudanetworks.com.:
<<< 550 permanent failure for one or more recipients (rejecting banned content)
554 5.0.0 Service unavailable
How do I fix this?
