# User Management
|
||
|
|
|
||
|
|
## Accounts
|
||
|
|
|
||
|
|
Users (email accounts) are managed in `/tmp/docker-mailserver/postfix-accounts.cf`. The best way to manage accounts is to use the reliable `setup` command inside the container. Just run `docker exec <CONTAINER NAME> setup help` and have a look at the section about subcommands, specifically the `email` subcommand.
|
||
|
|
|
||
|
|
### Adding a new Account
|
||
|
|
|
||
|
|
#### Via `setup` inside the container
|
||
|
|
|
||
|
|
You can add an account by running `docker exec -ti <CONTAINER NAME> setup email add <NEW ADDRESS>`. This method is strongly preferred.
|
||
|
|
|
||
|
|
#### Manually
|
||
|
|
|
||
|
|
!!! warning
|
||
|
|
|
||
|
|
This method is discouraged!
|
||
|
|
|
||
|
|
Alternatively, you may directly add the full email address and its encrypted password, separated by a pipe. To generate a new mail account data, directly from your host, you could for example run the following:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
docker run --rm -it \
|
||
|
|
--env MAIL_USER=user1@example.com \
|
||
|
|
--env MAIL_PASS=mypassword \
|
||
|
|
ghcr.io/docker-mailserver/docker-mailserver:latest \
|
||
|
|
/bin/bash -c \
|
||
|
|
'echo "${MAIL_USER}|$(doveadm pw -s SHA512-CRYPT -u ${MAIL_USER} -p ${MAIL_PASS})" >>docker-data/dms/config/postfix-accounts.cf'
|
||
|
|
```
|
||
|
|
|
||
|
|
You will then be asked for a password, and be given back the data for a new account entry, as text. To actually _add_ this new account, just copy all the output text in `docker-data/dms/config/postfix-accounts.cf` file of your running container.
|
||
|
|
|
||
|
|
The result could look like this:
|
||
|
|
|
||
|
|
```cf
|
||
|
|
user1@example.com|{SHA512-CRYPT}$6$2YpW1nYtPBs2yLYS$z.5PGH1OEzsHHNhl3gJrc3D.YMZkvKw/vp.r5WIiwya6z7P/CQ9GDEJDr2G2V0cAfjDFeAQPUoopsuWPXLk3u1
|
||
|
|
```
|
||
|
|
|
||
|
|
### Quotas
|
||
|
|
|
||
|
|
- `imap-quota` is enabled and allow clients to query their mailbox usage.
|
||
|
|
- When the mailbox is deleted, the quota directive is deleted as well.
|
||
|
|
- Dovecot quotas support LDAP, **but it's not implemented** (_PRs are welcome!_).
|
||
|
|
|
||
|
|
## Aliases
|
||
|
|
|
||
|
|
The best way to manage aliases is to use the reliable `setup` script inside the container. Just run `docker exec <CONTAINER NAME> setup help` and have a look at the section about subcommands, specifically the `alias`-subcommand.
|
||
|
|
|
||
|
|
### About
|
||
|
|
|
||
|
|
You may read [Postfix's documentation on virtual aliases][postfix-docs-alias] first. Aliases are managed in `/tmp/docker-mailserver/postfix-virtual.cf`. An alias is a full email address that will either be:
|
||
|
|
|
||
|
|
- delivered to an existing account registered in `/tmp/docker-mailserver/postfix-accounts.cf`
|
||
|
|
- redirected to one or more other email addresses
|
||
|
|
|
||
|
|
Alias and target are space separated. An example on a server with `example.com` as its domain:
|
||
|
|
|
||
|
|
```cf
|
||
|
|
# Alias delivered to an existing account
|
||
|
|
alias1@example.com user1@example.com
|
||
|
|
|
||
|
|
# Alias forwarded to an external email address
|
||
|
|
alias2@example.com external-account@gmail.com
|
||
|
|
```
|
||
|
|
|
||
|
|
### Configuring RegExp Aliases
|
||
|
|
|
||
|
|
Additional regexp aliases can be configured by placing them into `docker-data/dms/config/postfix-regexp.cf`. The regexp aliases get evaluated after the virtual aliases (container path: `/tmp/docker-mailserver/postfix-virtual.cf`). For example, the following `docker-data/dms/config/postfix-regexp.cf` causes all email sent to "test" users to be delivered to `qa@example.com` instead:
|
||
|
|
|
||
|
|
```cf
|
||
|
|
/^test[0-9][0-9]*@example.com/ qa@example.com
|
||
|
|
```
|
||
|
|
|
||
|
|
### Address Tags (Extension Delimiters) as an alternative to Aliases
|
||
|
|
|
||
|
|
Postfix supports so-called address tags, in the form of plus (+) tags - i.e. `address+tag@example.com` will end up at `address@example.com`. This is configured by default and the (configurable!) separator is set to `+`. For more info, see [Postfix's official documentation][postfix-docs-extension-delimiters].
|
||
|
|
|
||
|
|
!!! note
|
||
|
|
|
||
|
|
If you do decide to change the configurable separator, you must add the same line to *both* `docker-data/dms/config/postfix-main.cf` and `docker-data/dms/config/dovecot.cf`, because Dovecot is acting as the delivery agent. For example, to switch to `-`, add:
|
||
|
|
|
||
|
|
```cf
|
||
|
|
recipient_delimiter = -
|
||
|
|
```
