Your VPS can also host business email accounts.
Steps:
-
Install and configure mail server software such as Postfix or Exim.
-
Add DNS records: MX, SPF, DKIM, and DMARC for reliable delivery.
-
Use a mail client or webmail to access emails.
-
Monitor blacklists to ensure your IP is not blocked.
Running an email server requires careful setup to avoid spam issues, but it gives you full control.
