Settings¶

Below you can find the currently available email-related settings. Most of these settings have default values which can be found in this list as well.
Note
Some email-related settings are ticket-based settings, which is why they can be found in the Composer Settings.
List of Settings¶
- Notification Sender: Default value
Notification Master <noreply@#{config.fqdn}>
This is the default sender address for Zammad that affects all mails but those generated because of replies (like triggers or agent-based mails). Your customers normally will not see this address. This email address does not need to receive and can’t be assigned to a group.
Note
This address is relevant for agent notifications and password reset mails (also affects customers).
- Additional follow-up detection
In some situations the normal follow-up detection is not enough. This might be due to missing references in the subject (the ticket hook and number). These options can help to recognize follow-ups to existing tickets.
Note
Please note that searching in attachment and body might lead to false follow-up detection.
- Maximum Email Size: Default value
10 MB
This one is pretty obvious: It defines the maximum allowed size of an email Zammad will fetch. Zammad will not fetch Mails that are bigger than this option.
Hint
This technically also affects attachments for articles.
- Send postmaster mail if mail too large: Default value
yes (enabled)
Note
Upgraded installations will, by default, have the value set to
no (disabled
).- Option set to
yes
This setting will cause Zammad to automatically reply to mails that exceed the above mail size limit with a postmaster style mail. This will help your user to understand that his mail did not arrive and won’t be reviewed by you.
Note
Zammad will still download and remove (if enabled) the mail from the mailbox. Instead of importing it to the database, it will save the affected mail to
/opt/zammad/tmp/oversized_mail/
.- Option set to
no
If the option is set to no, Zammad will not reply to mails that are too big. Your customer will not notice that the mail was too large! Instead, Zammad will use the monitoring endpoint to alert its administrators that it can’t fetch a too large mail.

- Option set to
- Sender based on Reply-To header: Default value
not set (-)
This setting decides how Zammad should recognize its customers from emails that contain a
Reply-To
header. This comes in useful if you’re working with contact forms that need to use reply to headers.- Option set to
Take reply-to header as sender/from of email.
This setting will overwrite the initial
FROM
to the value used inReply-To
completely.- Option set to
-
orTake Reply-To header as sender/from of email and use the real name of origin from.
This setting will partially overwrite the initial
FROM
. It uses the mail address from theReply-To
header and uses the given name of theFROM
header, if given.
- Option set to
- Customer selection based on sender and receiver list: Default value
yes
This option decides how Zammad should react if an agent sends a email to it.
- Option set to
yes
The first user / email address from the recipient list will be used as the ticket customer.
- Option set to
no
The agent will be set as ticket customer.
Note
Currently agents can’t be customers within the UI. While Email communication works, agents can’t see their own tickets (as a customer) if they don’t have access to the group.
- Option set to
- Block Notifications
With the regex that can be defined here, you can ensure not to send any notifications to specific systems. By default this especially affects typical system addresses which can’t receive emails anyway.
The default value is:
(mailer-daemon|postmaster|abuse|root|noreply|noreply.+?|no-reply|no-reply.+?)@.+?
- Sender Format: Default value
Agent Name + FromSeparator + System Address Display Name
This configures the display name used in the
FROM
header of mails Zammad sends.Note
This does not affect Notification mails (to agents) and password reset mails. Emails that are not sent by agents (e.g. trigger-based notifications) will always fallback to
System Address Display Name
if needed.- Option set to
Agent Name + FromSeparator + System Address Display Name
This will cause Zammad to set the
FROM
header to agent name and the channel’s display name, divided by a separator (configured below).Example:
Christopher Miller via Chrispresso Inc.
.- Option set to
System Address Display Name
This will cause Zammad to always use the display name of the used channel in the
FROM
header.Example:
Chrispresso Inc.
- Option set to
Agent Name
Zammad will use the agent’s name which is very personal.
Tip
Usually you’d also want to remove the ticket slug from the subject in those cases.Learn more in Settings → Ticket.
- Option set to
- Sender Format Separator: Default value
via
This can be a string you can freely choose. It divides the agent’s name and the display name of the channel whenever needed.
- Ticket Subject Forward: Default value
FWD
The above string will be used on the subject if you forward an email from Zammad.
Note
:
will be automatically appended to the above string.- Ticket Subject Reply: Default value
RE
The above string will be used on the subject if you reply to a mail from Zammad.
Note
:
will be automatically appended to the above string.- Ticket Subject Size: Default value
110
This setting enforces a maximum length for subjects when replying. If the subject you’re using for your reply is too long, Zammad will automatically truncate the length and insert
[...]
to show it has shortened the subject.Example:
RE: Test somew[...] [Ticket#123456]
Note
This does not limit ticket titles within the UI, just the subjects when replying to an email.
Enhanced settings¶
Some less relevant settings can be changed via rails console if needed. As an example, Zammad allows you to send all outgoing communication to a BCC address for archiving reasons if needed. You can find the needed commands within the advanced customization settings.
