I am running several websites on a Windows VPS that have "recommend this to a friend" type of emails. I get frequent bounces.
The provider allows us to configure reverse DNS records for all the domains that are hosted on the server, which I did recently. The changes have propagated. I am doing this through their administration panel and I am not sure what happens behind the scenes.
I am still getting these errors in the log:
2009-09-22 22:07:50 200.221.XX.XXX OutboundConnectionResponse SMTPSVC1 XXXXXXX - 25 - - 450+4.7.1+Client+host+rejected:+cannot+find+your+hostname,
Is this not related to reverse DNS issues? Or this just a notorious mail exchange (mx.uol.com.br)? How can I verity that our server is correctly configured?
