+[Traefik](/wiki/traefik.md).
+In this case a 504 error will be displayed.

+
+#### `sqlite3.OperationalError: no such column: books.isbn`
+
+When starting calibre's web version a `500 Internal Server Error` may be displayed.
+The logs contain an error similar to the following.
+
+```txt
+sqlite3.OperationalError: no such column: books.isbn
+```
+
+This indicates that the `metadata.db` schema is missing the `isbn` and `flags` columns expected by
+the installed web version.
+
+As a temporary workaround the missing columns can be added manually using the following command.
+The placeholder `<metadata>` is the path to calibre's `metadata.db`.
+
+```sh
+sqlite3 <metadata>
+```
+
+Afterwards run the following [SQL](/wiki/database.md) commands on the database.
+
+```sql
+ALTER TABLE books ADD COLUMN isbn TEXT;
+ALTER TABLE books ADD COLUMN flags INTEGER NOT NULL DEFAULT 0;
+```
+
+After applying the changes restart the service.
+
+The added columns are metadata fields.
+Existing books will keep a `NULL` value for `isbn` and `0` for `flags`.
+This workaround allows the web version to start again, however it is recommended to verify that the 
+library was created with a compatible calibre version and that the correct `metadata.db` is being
+used.

+```sh

+```
 
-Afterward you're ready to go by once again running the `rebuild.sh` file.
+Finally rebuild the container once again.
+
+The required DNS configuration is explained in the
+[corresponding section of the email wiki entry](/wiki/email.md#mail-server-records).
+This needs to be set up for the [email](/wiki/email.md) to work properly with most other providers.
+
+For the DKIM record the generated configuration has to be retrieved from the following file.
+
+```txt
+config/opendkim/keys/<domain>/mail.txt
+```
+
+Afterward run the `rebuild.sh` file again.
+
+### Reverse proxy
 
 If setting up this mailserver with [Traefik](/wiki/traefik.md) as a reverse proxy some additional
 steps should be taken.
-No http or https is needed.
-But a certificate for the mailserver is needed regardless.
-In this case add the following lines to the file `docker-compose.yml` in the
-`services:` section and adapt them.
+
+Although SMTP, IMAP and POP3 do not pass through [Traefik](/wiki/traefik.md), a TLS certificate is
+still required.
+A simple way to automatically obtain and renew such a certificate is to expose a temporary HTTP
+service.
+In this case a simple [Traefik](/wiki/traefik.md) `whoami` container is used.
+
+For a single mail domain the following service is sufficient.
+In this case add the following lines to the file `docker-compose.yml` in the `services:` section and
+adapt them according to your needs.
 
 ```yml
-  whoami:
-    image: docker.io/traefik/whoami:latest
-    labels:
-      – "traefik.enable=true"
-      – "traefik.http.routers.whoami.rule=Host(`<subdomain>.<domain>`)"
+whoami:
+  image: docker.io/traefik/whoami:latest
+  networks:
+    - proxy
+  labels:
+    - "traefik.enable=true"
+    - "traefik.http.routers.whoami.rule=Host(`mail.<domain>`)"
+    - "traefik.http.routers.whoami.tls=true"
+    - "traefik.http.routers.whoami.tls.certresolver=letsencrypt"
 ```
 
+The mailserver itself does not use this service.
+It merely causes [Traefik](/wiki/traefik.md) to request and automatically renew the TLS certificate.
+
+### Optional: Multiple Mail Domains
+
+Multiple independent mail domains can share a single mailserver instance.
+In this setup only one TLS certificate is used, containing all mail hostnames as Subject Alternative
+Names (SANs).
+
+For two domains the configuration could look as follows.
+
+```yml
+whoami:
+  image: docker.io/traefik/whoami:latest
+  networks:
+    - proxy
+  labels:
+    - "traefik.enable=true"
+    - "traefik.http.routers.whoami.rule=Host(`mail.example.com`) || Host(`mail.example.org`)"
+    - "traefik.http.routers.whoami.tls=true"
+    - "traefik.http.routers.whoami.tls.certresolver=letsencrypt"
+    - "traefik.http.routers.whoami.tls.domains[0].main=mail.example.com"
+    - "traefik.http.routers.whoami.tls.domains[0].sans=mail.example.org"
+```
+
+For three domains simply extend both the router rule and the SAN list.
+
+```yml
+- "traefik.http.routers.whoami.rule=Host(`mail.example.com`) || Host(`mail.example.org`) || Host(`mail.example.net`)"
+- "traefik.http.routers.whoami.tls.domains[0].main=mail.example.com"
+- "traefik.http.routers.whoami.tls.domains[0].sans=mail.example.org,mail.example.net"
+```
+
+[Traefik](/wiki/traefik.md) will then obtain a single certificate with the following names and keep
+it updated in the future.
+
+- `mail.example.com` as the Common Name (CN)
+- `mail.example.org` as a Subject Alternative Name (SAN)
+- `mail.example.net` as a Subject Alternative Name (SAN)
+
+This single certificate is used by the mailserver for all configured mail domains.
+
+For every additional domain  a DKIM key has to be generated.
+
+```sh
+docker exec mailserver setup config dkim domain '<domain>'
+```
+
+The required DNS records described in the
+[corresponding section of the Email entry](/wiki/email.md#mail-server-records) also have to be
+created as previously shown in [the previous section](#initial-configuration).
+
+After that mail addresses for the additional domains can simply be created and used.
+No further setup is needed and [emails](/wiki/email.md) using the new domains can simply be created.
+
+```sh
+./setup.sh email add <user@domain.tld> (<password>)
+```
+
+### Optional: Client Setup
+
+After setting up the [Email](/wiki/email.md) server, some [Client](/wiki/email.md#client)
+configurations may be taken.
+Especially recommended is the setup of
+[end-to-end encryption](/wiki/email.md#end-to-end-encryption).

 - [Dovecot](/wiki/docker/mailserver_-_docker-mailserver.md) is a simple dockerized
   mail server that has no interface.
 
+### Mail Server Records
+
+To successfully operate a mail server several DNS records are required.
+The following records assume that the mail server is reachable via `mail.<domain>`.
+
+#### Mail A Record
+
+The mail host must resolve to the server's public IP using an [A record](#a-record).
+
+```txt
+mail.<domain>.    A      <server-ip>
+```
+
+#### MX record
+
+The MX record specifies which host is responsible for receiving mail for the domain.
+For this an [MX Record](/wiki/dns.md#mx-record) is used.
+
+```txt
+<domain>.         MX     10 mail.<domain>.
+```
+
+The target of an MX record must always resolve to an [A](/wiki/dns.md#a-record) or
+[AAAA record](/wiki/dns.md#aaaa-record).
+
+#### SPF record
+
+SPF specifies which servers are allowed to send mail on behalf of the domain using a
+[TXT record](/wiki/dns.md#txt-record).
+
+```txt
+<domain>.         TXT    "v=spf1 mx -all"
+```
+
+If mail is only sent via the configured mail server this is sufficient.
+If additional providers are used the SPF record maybe has to be extended accordingly.
+
+#### DKIM record
+
+DKIM allows receiving mail servers to verify that an email has not been altered during transport.
+
+The DKIM key is generated by the mail server and published as a
+[TXT record](/wiki/dns.md#txt-record).
+
+```txt
+mail._domainkey.<domain>.    TXT    "v=DKIM1; h=sha256; k=rsa; p=<public-key>"
+```
+
+The key has to be retrieved from the mail server.
+For example for [docker-mailserver](/wiki/docker/mailserver_-_docker-mailserver.md) the process is
+described in the
+[corresponding setup section](/wiki/docker/mailserver_-_docker-mailserver.md#setup).
+
+#### DMARC record
+
+DMARC defines how receiving mail servers should handle messages that fail SPF or DKIM validation.
+The DMARC records is a specific [TXT record](/wiki/dns.md#txt-record).
+
+```txt
+_dmarc.<domain>.    TXT    "v=DMARC1; p=none; rua=mailto:dmarc@<domain>; adkim=s; aspf=s"
+```
+
+After verifying that SPF and DKIM work correctly the policy can be changed to
+
+```txt
+p=quarantine
+```
+
+or
+
+```txt
+p=reject
+```
+
+#### Reverse DNS Record
+
+The server's IP address should resolve back to the mail host.
+This is done using a [PTR record](/wiki/dns.md#ptr-record).
+Please note that PTR records can not be set as easily as normal DNS records as explained in
+[the corresponding section of the DNS entry](/wiki/dns.md#ptr-record).
+
+```txt
+<server-ip>    PTR    mail.<domain>.
+```
+
+The PTR record is configured at the hosting provider and not in the domain's DNS zone.
+
+It is recommended that the PTR record matches the hostname used by the mail server's HELO/EHLO
+greeting.
+
+### Administrative addresses
+
+For interoperability every mail domain should provide at least the following addresses.
+
+- `postmaster@<domain>`
+- `abuse@<domain>`
+- `dmarc@<domain>` (recommended if DMARC reports are enabled)
+
+These addresses may simply be aliases that forward to the primary mailbox.

+### End-to-End Encryption
+
+Besides transport encryption (TLS), emails can also be protected using end-to-end encryption.
+The two most common standards are [OpenPGP](/wiki/openpgp.md) and S/MIME.
+OpenPGP allows emails to be digitally signed and encrypted.
+Unlike TLS, which only protects the transport between mail servers and clients, OpenPGP protects the
