Can You Recommend Any Self-Hosted, Open-Source SMTP System

[pmjcreations]

Hello,

I am looking for a self-hosted email system like SendGrid.

The system should help me with:

• Build IP reputation, monitor, and scale.
• Opening and link click tracking.
• Ability to hold potential spam emails for manual review.
• Ability to automatically block/hold emails based on conditions like subject line and body copy filtering.
• Manage various lists like black, grey.
• All DNS and security measures.

I also prefer nice/modern UI. And the system should be capable of acting as an SMTP smart host with DirectAdmin.

I have seen https://mailinabox.email/ and https://postal.atech.media/. However, I haven't tested it yet. So I thought to ask here first.

Can you recommend any self-hosted, open-source SMTP system?

Hi @bdacus01

The email can be both transactional and marketing. It can be from any domain hosted in my DirectAdmin.

In short, my use case is this: https://help.directadmin.com/item.php?id=153

And I am currently running this exact way but with a third-party SMTP provider. I wish to host the SMTP server myself so that I can have more control.
