+==== enterprise vs. free ====
+PMG is free open source software with an optional enterprise subscription. For a private person, the enterprise license is too expensive, but if you use this setup for a production server in a copmany, you might want to consider getting the enterprise subscription, because besides support, it also offers access to an enterprise repository, which contains heavily tested packages whereas the non-subscription repo is kind of the "beta tester" repo, meaning, a new package gets to the no-sub repo first and only after a certain amount of time of successful distribution through the no-sub repos will it enter the enterprise repo. So you either contribute by testing new packages or by paying money :)
+by default, PMG comes with the enterprise repo pre-configured which means you won't be able to update if you don't have a subscription. if you want to use the free repo, you need to change your apt configuration:
+  rm /etc/apt/sources.list.d/pmg-enterprise.list
+  echo "deb http://download.proxmox.com/debian/pmg buster pmg-no-subscription" >> /etc/apt/sources.list.d/pmg-no-sub.list
+as a non-enterprise user you will have to run updates from the command line, while enterprise users can do it from the web-ui IIRC (i am a poor private user ;))
+===== Create new users =====
+to manage user accounts, login to adminer to edit your ''mailserver'' database.
+first make sure the domain is added by checking the ''domains'' table. if the domain does not exist, add it.
+make note of the domain id of the domain you want to add a new user for.
+to add a new forwarding, make a new entry in the ''aliases'' table, make sure you don't forget to fill in the ''domain_id'' field
+to add a new user account, make a new entry in the users table. make sure you don't forget to fill in the ''domain_id'' field. leave ''quota'' empty or 0 in order to not enforce a mail box quota. if you want to set a quota, enter the amount of space the mailbox is allowed to use **in bytes**. for the ''password'' field, you need to generate a password hash on the command line of your mailserver. use the command
+  dovecot pw -s SHA256-CRYPT
+and then enter the new password. It will return a SHA hash which you can then enter in the password field.
+lastly, to activate the new mail user account, send an email to that address.
+===== add a new domain =====
+to add a new domain to the mail system, complete the following steps:
+  - add the domain on the Proxmox Mail Gateway to the "Relay Domains" list
+  - add the domain to your mailserver database, as mentioned above
+  - update the DNS records of your domain to point to the mailfitler and also add these entries: <code>
+autoconfig              IN      CNAME   mail
+autodiscover            IN      CNAME   mail
+_dmarc                  IN      TXT     "v=DMARC1; p=quarantine; pct=100"
+@                       IN      TXT     "v=spf1 mx ~all"
+00000000._domainkey     IN      TXT     ( "v=DKIM1; h=sha256; k=rsa; ".... copy/paste from PMG
+</code>you can get the correct entry for he DKIM1 key from your proxmox mail gateway web gui, just go to Configuration --> Mail Proxy --> DKIM and click on the "view DNS record" button, then copy/paste the entry to your bind config.
