Host your own SMTP Server for Dev

Dear Dev, are you tired of dealing with email deliverability issues? Are you tired of relying on third-party email services that charge you hefty fees? You don’t have to struggle anymore. In this article, we will guide you on how to host your own SMTP Server.

What is an SMTP Server?

SMTP stands for Simple Mail Transfer Protocol. An SMTP server is responsible for sending and receiving emails between servers.

When you send an email, your email client connects to your SMTP server, which then routes your email to the recipient’s SMTP server.

How does an SMTP server work?

When you send an email, your email client connects to the SMTP server using the SMTP protocol. The SMTP server then checks the sender’s domain name and the recipient’s domain name to determine where to route the email.

The SMTP server then sends the email to the recipient’s SMTP server, which then delivers the email to the recipient’s email client.

Why should you host your own SMTP Server?

Hosting your own SMTP server has many benefits. You can have complete control over your email deliverability and avoid the fees charged by third-party email services.

Additionally, hosting your own SMTP server can improve your email’s reliability and security. You can monitor your email traffic and ensure that your emails are delivered efficiently.
