Hello ,

I have an Exchange 2013 Installation all in one server . Also i have setup an Edge role for this Exchange installation. In the Edge server i installa forefront protection for exchange for antispaming.

I have a very strange problem. I have a specific user that can't receive email from a specific domain . In edge roles i see 5.1.0 Sender denied,0,1,, .

I have manually add the whole sender domain to forefront white lists but i get the same sender denied error.

Any ideas ?

What values do you have in the Send connector? Is the user authenticated?

The user receiving the email is authenticated . It is a local user. What do you mean what values ?

SMTP Error 510 : Bad email address. This status code
is generated by the sender’s local mail server.
If the email was addressed internally, then it means that
the addressee, as written in the email’s TO, CC, or BCC
fields, does not exist in your organization’s email system.
If the email was addressed externally, then the recipient’s
email address was misspelt.
