Sending eMail thru the Webmail with a user autenticated by Active Directory on a relay SMTP doest not work.

It actually sends the eMail but if the AD domain is not a valid internet domain, it will just be lost somewhere.

Since users autenticated by Active Directory can not change there "From" address the mail is just lost when the internal AD domain is not a valid internet adddress

With Internal user, it's possible to change the "from" header and the mail arrive fine.

Any suggestion ?

I'm not sure I follow. Are you saying your AD domain name is different from your mail domain name?

I don't follow either, but it sounds like you need to go into the KMS Admin Console->Configuration->Domains->Directory Service and ensure "Active Directory domain name is different from this mail domain name" is checked and that the textbox below it is filled in with the name of your Active Directory domain.

Be aware that your mail domain MUST be a valid Internet domain name. So I think one of two things have happened here:

1.) You need to perform the steps in the first paragraph.

or 2.) You've misconfigured KMS to use your Internet-invalid AD domain as your mail domain.

BTW, this is all covered in the fine manual, located at:

Specifically, this issue is at:

I recommend using the manual as the first stop when you have a problem. It'll get your problems fixed quicker.

Hope that helps!

Except for the RTFM comment, your reply did help.

The only way out was to change the primary email domain name to something different than the AD name. It was then possible to follow the manual ...
