uPort UUCP problems

[Pim van Vrijaldenhoven]

As a good friend I'm acting as the Unix guru at my old employer.  They
have a PC/AT running uPort Unix  version 2.2L.  The system is mostly
used for email purposes and has links to a site that runs Ultrix in
the same city and to to a site in the USA that runs 4.3BSD.  For more
than a year the system has been running flawlessly, but recently
problems have developed with the UUCP communication with the site in
the States.  Suddenly mail is returned with the message: "remote access
 to path/file denied".  The system has never been reconfigured since
it was brought up initially.  The mailer used is smail version 1.2.
Can anybody give clue what's happening.

Please mail your replies to either pim at philmds or pim at fehq.fluke.nl.

Thanks you very much.
