Thanks to all who replied, and for the input. The variable
SMTP_OCH_REJECT_RELAYS was added to the notes.ini file, but relaying is
still possible according to our ISP. NT 3.51 could be the problem, but
that's not a definitive answer. I don't see how the version of Lotus
Notes we're running has anything to do with it. It's the SMTP/Mime MTA
software running on the MTA that's the problem. No?
We do have a Cisco PIX firewall that is still running with it's generic
setup. According to Cisco documentation, outbound connections are
allowed while direct inbound connections are not. My thinking is that I
would need to reconfigure the PIX to deny any unwanted connections from
coming in. Any ideas on how to do this without preventing legitimate
connections from coming in or going out? Thanks in advance for your
help.
