[exim] exim accept no email with empty mail from:<>

Hello,


i have problems to sends emails to an foreign mailserver.
the foreign server gets the error message "550 sender verify failed".
the foreign server try to send a bounce message to my server and this failed.
the reason for this is that my server accept no emails
with empty "mail from:<>".
What can i do that my server accept bounce emails?

Thanks for any help.
