How to add * domain.com in safe-sender list ?

Here is a deal I've been trying to add * domain.com to safe-sender list but being denied with following error, agreed this is not a standard format but we have a requirement for a relaying application that needs to be allowed as such by adding * domain.com , alternatively is there a way i can add this to safe sender from server or some transport rule. please suggest ?


Remark:- I do not need to add domain.com in accepted domains.

[PS] C:\Windows\system32>Set-MailboxJunkEmailConfiguration -Identity Aditya.@xyz.com -TrustedSendersAndDomains "* domain.com"

Can't update TrustedSendersAndDomains because it contains an invalid address.

Hi Philip,

Thanks for your valuable time however idea is not to include '@' and add safe-sender by * domain.com to allow anything preceding prior to domain ( relaying application uses several addresses without @ as well).

Hi Aditya,

Actually, * symbol is not a valid symbol here. So you have to add the name without * symbol. Also try to use domain.com alone instead of @domain.com. You can add multiples names too

Hi,

How about use Transport rule? For example:
Condition: The sender address matches "domain.com"
Action: Set the spam confidence level (SCL) to -1
Note: SCL: -1 means that non-spam coming from a safe sender, safe recipient, or safe listed IP address (trusted partner) and will be delivered to recipients inbox.

Thanks
