Exchange 2013 Relay doesn't send mail from printer to groups. only members.

Hello everyone,

I have deployed Exchange 2013 "Migration" and created a relay for printers and added all their IPs however after configuring them "xerox 5665" the email doesn't get forwarded to Exchange groups. only users!

I wonder if there's anything needed to configure! I have 4 Exchange servers "2 MB and 2CAS" .

Would appreciate your help.

Groups by default will have the option that all senders must be authenticated.
You need to turn that option off in the properties of the group.

Hi Simon, where is this option ? Is it in receive connector? I couldn't find it!

I have created the receive connector in the mailbox server role! Is this configuration correct?

I have tried to create the connector on the CAS role but when I apply the AD Permission it doesn't find it and it only looks at the second MB server role.

Get-ReceiveConnector -Identity 'Relay Connector' | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "ms-Exch-SMTP-Accept-Any-Recipient"
The settings which Simon talking about is on Group itself.

EMC -> Recipient Config -> distribution groups => find the group -> right click properties -> mail flow settings -> message delivery restriction and UNCHECK "require that all senders are authenticated"
