Hello, When I send fax from extension 55 to extension 66 it seems that the fax is recieved, because I can se it in "Fax Visor". But the corresponding e-mail does not send. In the maillog I see that the smtp server of my domain reject the addres email@example.com, because the domain kinfor.local does not exists: 550 <uucp@Kinfor.local>: Sender address rejected: Domain not found (in reply to RCPT TO command)) here "@Kinfor.local" is my local domain, but who is "uucp" that try to send the e-mail to me? In my virtual fax list I have two fax extension 55 and 66 and they have configured another e-mails. Thank you.
