How can I set up my own server SMTP with an open source Mailing software?

[TheTruth]

Most of the email sending platforms charges a lot. Besides, you can even be removed from their platform without prior notice. How can one set up and run his own email server?

You need to set up a MTA and a mailing program Message transfer agent - Wikipedia
If you have the tech skills it is usually a challenge unless you are experienced in managing mail servers.

That's just to get started --then you have to understand the intricacies of bulk mailing to manage an email list effectively.

Down side is: the internet has to trust your unknown mail server --otherwise it is a wasted effort.

@TheTruth,
I experienced over 10 years in email delivery and I don't see any good opensource Mailing Software. You may try this SMTP Service Home | VIPLinkMedia it has a free trial to send 500K emails. You may order dedicated SMTP server for you too.
