Hi folks.
I've got ucspi-tcp-0.88 with rblsmtpd and qmail-1.03 on FreeBSD 4.0.
We recently had some problems where a large part of our area network was
working fine, but our link to the outside world was having problems and
periodically went down. This meant that when an smtp connection was made
to our server, the conversation couldn't happen because rblsmtpd couldn't
connect to the RBL server to do the lookup. Despite not having an
internet connection, there were still lots of messages that could be
delivered locally, and it would have been nice if they'd gone through.
I looked through the rblsmptd documentation and related sites and couldn't
find anything that mentions this sort of behavior.
A few questions, then:
-If rblsmtpd can't talk to the RBL server, what sort of error does it
issue to the connecting server? Temporary or permanent? Is it just the
default 60 second timeout?
-Is there a way to tell rblsmtpd to "carry on like normal" if the lookup
doesn't happen in the first X seconds? The "-t" option appears to be a
timeout related option, but doesn't seem to do this particular thing.
-Any other bits of advice/strategy for rblsmtpd being used in that sort
of situation?
Thanks,
Chris
