# Documentation and information relating to my self-hosted mail server
|
|
|
|
## Brief Architecture Overview
|
|
|
|
- Postfix is used as the SMTP server and Dovecot is used as the IMAP server
|
|
|
|
- TLS certs are obtained via lets encrypt
|
|
|
|
- OpenDKIM is used for signing paired with SpamAssassin for mail filtering
|
|
|
|
## Features
|
|
|
|
- Appropriate DNS records [(SPF, PTR, DKIM, DMARC)](https://git.tobiastime.xyz/Tobias/Mail-Server/raw/branch/main/images/mailpass.webp) implemented for authentic, trusted and reliable mail. Full report available [here](https://git.tobiastime.xyz/Tobias/Mail-Server/raw/branch/main/images/full_report.txt)
|
|
|
|
- DNSSEC enabled for Postfix allowing validated MX lookups, with DNSSEC additionally configured for the server's domain to protect the [integrity of record resolution](https://git.tobiastime.xyz/Tobias/Mail-Server/raw/branch/main/images/dnssec.png)
|
|
