# Email
## Purpose
Choose the email environment before following a deployment or repair procedure.  Mailcow with PMG, iRedMail, Microsoft Exchange, and the cPanel scaffold describe separate configurations; their presence here does not establish that they are all active in the lab.

## Includes
- Mailcow and PMG integration
- iRedMail deployment and connection settings
- Exchange maintenance and DAG recovery

## Mailcow and PMG
- [Deploy Mailcow](<../../../deployments/Applications/Email/mailcow.md>) — Configure the mail service and its documented proxy arrangement.
- [Integrate PMG with Mailcow](<../../../deployments/Applications/Email/Proxmox Mail Gateway/Integrate PMG with Mailcow.md>) — Follow the gateway, DNS, NAT, and mail-flow integration.
- [Repair Trusted Mail Delivery](<../../../workflows/Applications/Email/Proxmox Mail Gateway/Repair Trusted Mail Delivery Between PMG and Mailcow.md>) — Investigate sender-validation or relay-trust failures after integration.

## iRedMail
- [Deploy iRedMail](<../../../deployments/Applications/Email/iRedMail/Deploy iRedMail.md>) — Follow the separately documented mail-server implementation.
- [Client Connection Settings](<iRedMail Connection Settings.md>) — Find the recorded protocol and server settings.
- [Inspect the SMTP Queue](<../../../workflows/Applications/Email/iRedMail/Inspect the Outgoing SMTP Queue.md>) — Investigate outgoing messages on the iRedMail environment.

## Microsoft Exchange
- [Exchange SE Rolling Updates](<../../../workflows/Applications/Email/Microsoft Exchange/Perform Exchange SE DAG Rolling Updates.md>) — Use the complete maintenance cycle for the explicitly described three-member example.
- [DAG Database Copy Repairs](<../../../workflows/Applications/Email/Microsoft Exchange/Manage DAG Database Copies.md>) — Review the older example and version context before applying its recovery commands.
- [Cumulative Update Preparation Notes](<../../../workflows/Applications/Email/Microsoft Exchange/Prepare for Cumulative Updates.md>) — Review the separate preparation procedure and its environment assumptions.
- [Certificate Packaging](<../../../workflows/Identity and Certificates/Certificates/Convert Certificates to PFX.md>) — Find the documented certificate conversion workflow.
