What should I do to not get listed
Conform to the standards
All email must comply with all relevant RFCs.
Ensure your rDNS is correct
Vade performs an rDNS check on the IP of the sending server. If the sending server does not have a PTR record and a MX or an A record set up properly, the connections will not be accepted.
Stay off DNSBL lists
Vade uses several DNSBLs including Vade Threat List and Validity. Being listed on any reputable, widely used DNSBL is likely to cause your email to be blocked not only by Vade, but other ISPs as well.
Practice good abuse management
Dictionary or Directory Harvest attacks are treated seriously and will quickly lead to the sending IP being blocked.
Keep it Static
Dynamic IP space is a common haven for compromised machines used in bot networks. Following industry best practices Vade lowers reputation of dynamic IP space.
Keep your IP reputation clean
Overall IP reputation is key to successfully sending to Vade. If Vade, or another reputable organization repeatedly receives spam, spyware or other malicious attacks, phishing or other deceptive emails from a certain IP address, Vade is more likely to block future messages from that IP address. Ensure the overall sending reputation of the sending mail system is as clean as possible.
Pay attention to error messages
Most non-delivery notifications Vade returns contain links to FAQs which explain why the block occurred and instruct in how to remediate the issue. Take the time to review any errors - it is likely they hold the key to a quick remediation. Visit our inbound error codes or outbound error codes pages.
Watch the sending limits
Vade allows at maximum 100 recipients per message. Vade applies a throttling rate based on your sender reputation and authentication.
