How many emails does your SMTP server send out daily? Whoa, a hundred! Maybe a thousand of them? Guide to Buy SMTP Server with Bitcoin.

Sending out newsletters and business proposals via bulk mail is crucial to your firm’s communication and relationships with clients.

There may be occasions when you get the “your email can’t be delivered” message. If you have a clean, well-maintained subscriber list, it’s common to have 5-10 letters out of every thousand bounces.

What will happen if 10% to 20% of your messages don’t get delivered? Unfortunately, this nightmare could become a reality if you’ve been labeled a spammer.

Nearly 90% of emails sent nowadays are junk. It’s no wonder, then, that spam avoidance is universal. Providers develop stricter anti-spam filters as filters attempt to block as much mail as possible. But, then, even when conducting lawful business, your messages may be intercepted.

When this occurs, you feel a great deal of distress. Let me see if I can show you how to configure your own SMTP server for sending emails and turn anti-spam filters into your ally. After that, anti-spam filters will welcome your messages like old friends whenever they arrive.

To begin, please refer to the image below. It lays out the entire journey that your email takes.

I assume your letter is not spam, and your opt-in list is in good shape. If that’s the case, these guidelines won’t be beneficial.

To do so, follow these five guidelines. These guidelines were developed to ensure that your communications are error-free before they reach their intended inbox. The concept of “assigning trust” is the foundation of modern spam filters. If they detect any suspicious activity, they will lower your trust score, and if it drops low enough, your letter will be deleted permanently.

If you want to do a mass mailing or set up your own outgoing mail SMTP server, you will need to accomplish the following:

* Obtain a dedicated static IP address

* Set up both authoritative and caching name servers

* Look into no-fly lists

* Set up SPF

Optionally, set up domain keys.

These things may look strange initially, but we’ll show you how easy they are in a moment.

Get a dedicated IP address.

This is not something you can expect to get automatically from your usual Internet provider in most cases. When you connect to the internet, you receive a “floating” or “dynamic” IP address, which differs each time. Most email servers will refuse to accept connections from a dynamic IP address, equivalent toa shifting target. So getting a static IP address from your service provider should be your first order of business.

Dual-direction name server lookup

Forward and reverse DNS resolution configuration is another must-do for your local outgoing mail SMTP server. A client must first query a name server to retrieve the IP address to create a connection. Name servers in a domain will contact their parents for help if they cannot fulfill a client’s request.

They can make an authentication system that proves the ‘s domain name owner is also the owner of the IP address used by the email SMTP server. This verification will significantly increase your credibility.

It’s just another way to track you down using your domain name if you go wrong and start spamming. Since most spammers and phishers prefer to use stolen or hijacked domains and IP addresses, this barrier is usually insurmountable. In addition, no service provider will allow domain registration without verification (often a credit card).

So-called A-records and PTR records are used for forward and reverse DNS resolves. These records are essential for DNS lookups and should be added to your DNS immediately. Additionally, they will openly facilitate your work online. You can inquire about this with your service provider or domain registrar. As a result, spam filters and other servers will start to trust you more.

Do not assume that your ISP has automatically configured the PTR record for your domain simply because you have set an “A record” of the domain name in your DNS. It would be best to double-check with them, as this feature isn’t always included.

Negative listing

A DNS query can reach a DNS blocklist, also known as a DNS block list. These are the databases where IP address lists are kept. They are employed in the blocking of spam-sending IP addresses. For example, if the mail server suspects that the message it received was spam, it will first ask the client’s IP address to confirm its presence.

If you know what went wrong, you can see if it’s on blocklist sites. Alternatively, you can utilize the manual instructions provided by most places to get your IP address removed.

SPF

The “sun protection factor” (SPF) is not what you think it is. The SPF DNS record is next and is also helpful but not required. It lists the computers authorized to deliver mail on behalf of a given domain. With the help of SPF, we can check if the sender’s IP address can send mail to this domain. If you send an email from a different IP address than your selected one, the server may reject it or mark it as spam.

Using an SPF record may prove your good faith to the target servers. The authoritative resource for SPF (Sender Policy Framework) DNS records is openspf.org. If you need assistance setting-up SPF, contact your domain registrar. The configuration panel of some of them includes specialized wizards. They can automate the process of setting up your SPF for you.

Optional Domain Keys

There is also another standard for inspection that is not as common. It’s debatable whether or not it’ll be beneficial. That’s because few service providers perform the check.

To verify the origin of an email, Domain Keys were developed. It’s pretty similar to SPF, except it adds encryption to ensure that only the appropriate people can send a given email.

As you can see, Domain Keys does not filter spam; however, by presenting a valid domain, spam filters are better able to do their job. To avoid being labeled a spammer.
