Mail delivery is a well-known cause of communication delays or failed deliveries. This is because email is considered a public domain and many spams and malicious email messages exist in circulation. If your email messages are getting rejected because they are in the wrong place or do not reach the right recipient, you should know that it is a normal and not unusual situation.
This tool checks all email address records of a website and helps you to see which ones are blacklisted and which are whitelisted. It checks both the domain name and the IP address of each website.
