Set up on email server (incl. DKIM/SPF) for bounces/ spam complaints (Ubuntu)

Job ID: 31826901

Budget: $30 – $250 USD

I need to set up multiple servers i.e. prod1, prod2 etc on several Ubuntu systems to send only OUTBOUND email.

I need a proof-of-concept installation and guideline to repeat (as as simple as possible) on subsequent installation.

I am aware of all the 'warming up'.

Whenever there is a spam complaint or bounce going back to the emails server (rare but it happens) our webhooks needs to be called i.e. example.com/register-spam.php?email=wasspam so we can account for it.

I can't pay more than $100. Please demonstrate your experience.
