Expert for MailWizz + PowerMTA Reply Routing

MailWizz + PowerMTA Reply Routing Specialist Needed

We are looking for an experienced MailWizz + PowerMTA email infrastructure specialist to fix our current reply-routing setup.

Current situation

We are sending campaigns through multiple sending domains using MailWizz + PowerMTA.

Currently, when a recipient clicks Reply, the Reply-To address exposes our central/main domain:

We need to change this architecture so that replies remain associated with the sending domain, while still being routed centrally.

Desired setup

For example:

Sender domain→ recipient

Recipient clicks Reply:

Sender domain

Then:

Sender domain → automatically forwarded/routed to our central mailbox.

We have multiple sending domains, so the solution needs to be scalable and manageable across all of them.

What we need

* Strong hands-on experience with MailWizz
* Strong experience with PowerMTA
* Experience configuring Reply-To / return-path / sending domains
* Experience with domain-level mail routing and forwarding
* Ability to configure the solution without breaking existing campaigns
* Proper SPF, DKIM and DMARC considerations
* Ability to test the complete flow using Gmail/Outlook
* Explain exactly what was changed and provide documentation
* Must understand the difference between From, Reply-To and Return-Path

Important

We are not looking for someone who simply changes the Reply-To field.

We need someone who understands the underlying mail infrastructure and can implement a proper domain-level reply-routing architecture.

Please do not apply if your experience is limited to basic MailWizz campaign setup.

When applying, please provide

1. Your experience with MailWizz + PowerMTA
2. Examples of similar reply-routing setups you’ve implemented
3. Whether you would handle the routing in MailWizz, PowerMTA, the mail server, or a combination — and why
4. Your estimated time and fixed/hourly cost
5. Any information you need from us to begin

We are looking for someone who can implement and test the complete solution, not just provide generic instructions.
