Mentioned below are the necessary that you have to follow when you begin the process of your outgoing SMTP server, or if you’re planning to setup SMTP server for bulk mailing:
• Get Static IP
Most or even all of your regular IP (Internet Providers) will not give you the IP address by default. Dynamic (or floating) IP address is assigned to you generally. This IP address changes at every point of time when you hook up to the Internet. The process is like hitting the moving target. You will be blocked by the majority of the email servers in case your link comes from this kind of dynamic IP. So your first priority would be to contact your Internet provider and receive the static IP address from them.
• Reverse & Forward DNS resolution
Another most important rule for local outgoing SMTP server – you need to take good care of is monitoring and configuring reverse & forward DNS resolution. DNS (or Domain Name Server) resolution happens when the potential customer queries the name server in order to get the desired IP address. This is required in establishing a connection. If you want to deliver your secure server email at right destination then there is the need to have the right SMTP server address. If the local DNS can’t resolve the request of a client, then this query is propagated to the parent servers in order to resolve the issue.

Try not to forget to include these types of records in the DNS – they are generally utilized for implementing or executing DNS lookups. Also, try to ask your domain registrar or provider to do this. So, you’ll be trusted with different servers and spam filters.
• DNS Block-list
DNS block-lists (or DNS blacklists) are usually accessed with the DNS query. This is the lists of various IP addresses which are stored in the remote database. It will block those IP addresses which are sending spam. SMTP mail server will verify the existence of client’s IP-address. If the client’s message is tracked as spam then that message will likely be blocked.
When you figure out the failure reasons you can test it with DNS blacklist website. You can also go with the manual directions of deleting the IP address from the list.
This is the optional and useful DNS record. It shows servers that have legal rights to deliver emails for a particular domain. SPF really helps to check whether the source sender’s IP is allowed to send messages for this particular domain. The host may reject or discard your mail or label it as a spam, in case you’re forwarding the secure server email from the IP which is other than the specified.
