It's me again!
Remember that spam relaying problem from last week
concerning our Domino email server being used to relay spam mail? The
problem had appeared to be fixed by late Thursday of last week. However,
today some people sending us mail have been rejected by our server. What
happened???!! Last Friday, we were sending and receiving email from
legitimate parties and we were not relaying spam mail. To refresh you, we
had to put the mail server's IP address and our users' IP's in the "Allow
messages only from the following external internet hosts to be sent to external
internet domains: ". That seemed to be working fine. But as of
today, some emails directed to us are being rejected due to "policy
reasons".
I had one person call saying they could not send us
an email. The message they were receiving was "Server Error: 554; Rejected
for Policy Reasons". I removed the IP addresses from the "Allow messages.
. . ." field and watched the console messages as this person sent the message
again. Everything came through just fine. But because I had to
remove those IP address entries, now we're open to relaying spam again. In
looking at the log files, some messages were allowed through, but sometimes, the
smtp server showed "0 messages received" once it was contacted by an external
computer. I also know that our messages to various email groups,
such as the yahoo groups, are being bounced back with the same
rejection code and policy reasons message. Does anyone have any ideas on
what to try now? Any suggestions would be greatly appreciated. I
really need help on this one!
We are running Domino 5.0.1 on OS/400 V4R4.
This problem just began about 2 weeks ago. We have made no configuration
changes or added/removed software/hardware.
Thanks for your time,
