Users (email accounts) are managed in `config/postfix-accounts.cf`. Just add the full email address and its encrypted password separated by a pipe. Example: user1@domain.tld|{SHA512-CRYPT}$6$2YpW1nYtPBs2yLYS$z.5PGH1OEzsHHNhl3gJrc3D.YMZkvKw/vp.r5WIiwya6z7P/CQ9GDEJDr2G2V0cAfjDFeAQPUoopsuWPXLk3u1 user2@otherdomain.tld|{SHA512-CRYPT}$6$2YpW1nYtPBs2yLYS$z.5PGH1OEzsHHNhl3gJrc3D.YMZkvKw/vp.r5WIiwya6z7P/CQ9GDEJDr2G2V0cAfjDFeAQPUoopsuWPXLk3u1 In the previous example, we added 2 mail accounts for 2 different domains. This is will automagically configure the mail-server as multi-domains. To generate a new mail account entry in your configuration, you could run for example the following: docker run --rm \ -e MAIL_USER=user1@domain.tld \ -e MAIL_PASS=mypassword \ -ti tvial/docker-mailserver:latest \ /bin/sh -c 'echo "$MAIL_USER|$(doveadm pw -s SHA512-CRYPT -u $MAIL_USER -p $MAIL_PASS)"' >> config/postfix-accounts.cf You will be asked for a password. Just copy all the output string in the file `config/postfix-accounts.cf`. The `doveadm pw` command let you choose between several encryption schemes for the password. Use doveadm pw -l to get a list of the currently supported encryption schemes. > Note: changes made with this script require a restart of the container. See [#552](../issues/552) *** ## Mailbox quota On top of the default quota (`POSTFIX_MAILBOX_SIZE_LIMIT`), you can define specific quotas per mailbox. Quota implementation relies on [dovecot quota](https://wiki.dovecot.org/Quota/Configuration) which requires dovecot to be enabled. Consequently, quota directives are disabled when `SMTP_ONLY=1` or when `ENABLE_LDAP=1` or when explicitly disabled with `ENABLE_QUOTAS=0.
A warning message will be sent to the user when his mailbox is reaching quota limit. Have a look at [90-quota.cf](https://github.com/tomav/docker-mailserver/tree/master/target/dovecot/90-quota.conf) for further details. ### Commands _exec in the container_ - `setquota []`: define the quota of a mailbox (quota format e.g. 302M (B (byte), k (kilobyte), M (megabyte), G (gigabyte) or T (terabyte))) - `delquota `: delete the quota of a mailbox - `doveadm quota get -u `: display the quota and the statistics of a mailbox ### `dovecot-quotas.cf` This file is a key-value database where quotas are stored. _dovecot-quotas.cf_ ``` user@domain.tld:50M john@other-domain.tld:1G ``` ### Notes - *imap-quota* is enabled and allow clients to query their mailbox usage. - When the mailbox is deleted, the quota directive is deleted as well. - LDAP ? Dovecot quotas supports LDAP **but it's not implemented** (_PR are welcome!_).
