I just retired my RH 7.2 sendmail server and replaced it with a RH 9 postfix server. I thought things were running well, but this morning I've been getting a lot of undeliverables with the message "host was found, but no data records of the requested type." Many messages go through, but many do not. I can try the same message 5-10 times and get the same error. Then if I do host -t MX <target-domain> it returns the needed address instantly. Then the next time I try to send the message it goes through.
If you watch tcpdump this whole time, you won't see the server even *try* to resolve the target domain. You do see it making and answering queries, just not the one you want. Then if you issue the host -t MX command, you see that in the trace. Then you see postfix send the e-mail. I think this started when I added acls to named.conf. Could this be because I didn't allow queries from 127.0.0.1? When postfix calls gethostbyname() does it do it from 127.0.0.1 or from the IP address bound to eth0? --Eric _______________________________________________ RLUG mailing list [EMAIL PROTECTED] http://www.rlug.org/mailman/listinfo/rlug
