Sender          Action Required
Sender not authorized for relay

How to Fix It
When Office 365 tried to send your message to the next server outside Office 365, that server reported an error that it couldn't relay your message. It's likely that the email server isn't correctly set up to receive and relay messages from your organization.
To fix this issue, forward this non-delivery report (NDR) to your email admin.

More Info for Email Admins
Status code: 550 5.7.367

The sender's message was routed to an email server outside Office 365 that returned an error that it can't relay the message. It's likely that the server isn't set up correctly to receive and relay messages sent from post.nuhet.se or from 19812_4781_730887_bounce.

The receiving server is not an Office 365 server - it's likely one of your on-premises servers in a hybrid environment, a server at a smart host email service that you're trying to route messages through, or possibly a server at an email hosting service you used in the past (for example, when your MX record still points to your previous email service provider). To fix this issue, try one or more of the following:

Check the error shown in the "Error Details" section below - Check the error to determine what domain, service, or server is reporting the error. The email server needs to be configured to either accept messages from anonymous users or to include the sending domain or sending IP address in its list of authenticated senders. On an on-premises Exchange server, you can set this up in the server's receive connector. If it's a smart host managed by another service or partner, contact the service or partner and ask them to configure their servers to accept and relay messages from your domain or from your senders.

Make sure your MX/DNS records are correct - Work with your DNS hosting provider (your domain registrar, Web hosting provider, or ISP) to make sure your MX records are correctly set up to direct messages to the correct location.

Unfortunately, Office 365 support can't help fix this problem because it's likely due to misconfigured settings on an email server outside Office 365.

Installationsteknisk energieffektivisering

Kurs om hur man driftoptimerar och energieffektiviserar byggnader

med installationstekniska åtgärder.

[https://post.nuhet.se/images/public/19812_442ff7927191982804457e72383f436b.JPG]

INSTALLATIONER AVGÖRANDE
All energi som köps till en byggnad distribueras genom installationer. Att dessa är välfungerande är en förutsättning för såväl lågt energibehov som bra inomhusklimat och det finns alltid åtgärder att göra för att ytterligare minska energianvändningen.

DU LÄR DIG
I kursen lär du dig att driftoptimera värme- och luftbehandlingssystem men också att analysera installationstekniska åtgärder för ytterligare energibesparingar. Stor vikt läggs vid mätning, analys och injustering men också vid metodiken att genomföra åtgärder i rätt ordning och i rätt kombination.

MÅLGRUPP
Energisparprojekt berör många aktörer och yrkesgrupper. Vi vänder oss till driftpersonal som arbetar med VVS- och energifrågor i fastigheter respektive energikonsulter och installatörer som involveras i energieffektiviseringsprojekt.

KURSLEDARE
Rickard Larsson är energiexpert på Aktea och flitigt anlitad av fastighetsägare som vill driftoptimera och energieffektivisera sina installationssystem. Hans arbetsuppgifter spänner över allt från energiutredningar, felsökning och driftoptimering till projektledning och installationssamordning.

Välkommen på kurs!
