Sendmail error: User unknown
I've configured sendmail as a mail relay server and it worked fine. Now I'v installed Vexira virusscanner for mailservers that uses port 25 and configured sendmail to use port 825. It worked a few times till now. I can connect to sendmail on port 825 with telnet, but it keeps telling me that the user I enter as rcpt to: is an unknown user. I only can send e-mail to local users (e.g. root, uucp and deamon). I've checked the configuration over and over again, but can't find the sollution. Any idea's?
Thanks in advance!
