Emails being rejected
Posted on 2014-02-12
This Monday I moved offices from one location to another. I received a new IP block. I modified my MX records and ptr records but did them incorrectly. I had incoming mail going to my Barracuda Spam device and outgoing mail leaving through my exchange server. When mail started being rejected I panicked and started sending mail outbound through my barracuda as well. So now I have my mx record pointing to barracuda and my ptr record resolving to barracuda. I made that last change today. Mail is still bring rejected. How can I validate that my current DNS configuration is good?. Does this take time to resolve? And if so how long before they will start being delivered?
Please help... My email has been unstable for 3 days now and things are not good!!
