Setup a smpt server quicky

I am looking for a freelancer to set up an SMTP server on a Linux operating system. The server will need to handle a medium volume of email traffic, specifically between 1000-5000 emails per day. Additionally, I require the server to have the capability to support a custom domain for email delivery.

Skills and experience required:
- Experience in setting up and configuring SMTP servers on Linux
- Knowledge of handling medium email traffic volumes
- Ability to configure email delivery with custom domains
