-The reason aliases with a custom domain are soft deleted (a deleted_at column if filled in the database) is to ensure that nobody else can register your same domain in the future and then sign up to our site and receive emails for aliases you have previously used.

+## Self Hosting
+
+#### Prerequisites
+
+* Postfix (2.7)+
+* PHP (7.1+) and the [php-mailparse](https://pecl.php.net/package/mailparse) extension
+* Port 25 unblocked and open
+* Redis (4.x+) not required if you don't need it for throttling or queues
+* FQDN as hostname e.g. mail.anonaddy.me
+* MariaDB / MySQL (or any other database compatible with Laravel)
+* Nginx
+* SpamAssassin, Amavis, OpenDKIM, OpenDMARC, postfix-policyd-spf-python
+* DNS records - MX, SPF, DKIM, DMARC
+* Reverse DNS
+* SSL/TLS Encryption - you can install a free certificate from Let’s Encrypt.
+
+#### Postfix configuration
+
+In /etc/postfix/master.cf you need to make sure it has this at the top:
+
+```cf
+smtp       inet  n       -       -       -       -       smtpd
+        -o content_filter=anonaddy:dummy
+```
+
+This should be the only line for smtp.
+
+Then add this these lines to the bottom:
+
+```cf
+anonaddy unix - n n - - pipe
+  flags=F user=youruser argv=php /path/to/your/webapp/artisan anonaddy:receive-email --sender=${sender} --recipient=${recipient} --local_part=${user} --extension=${extension} --domain=${domain} --size=${size}
+```
+
+Making sure to replace `youruser` with the username of the user who will run the artisan command and also to update the /path to your installation.
+
+This is what will pipe the email through to our applicaton so we can determine who the alias belongs to and who to forward the email to.
+
+More instructions to follow soon...
