Hi all,
it seems that the Postfix Daemon isn´t able to perform DNS Lookups. Customers reporting, that they don´t receive E-Mails anymore. I´ve checked the Logs and in fact Postfix always reports a "reject from unknown [X.X.X.X]". When I do a nslookup manually on those logged IP-Addresses, there is no problem and the DNS works without any problem except Postfix.
As Plesk is using BIND as a Resolver, the /etc/resolv.conf contains:
search foo.bar
nameserver 127.0.0.1
Again. Everything regarding DNS Lookups works great. Only Postfix doesn´t perform DNS Lookups for some reason and i´m not able to track down the issue. Does someone have an idea of what the problem can be?
Thank you!
