Postmaster Filters¶
Pre-sorting standard mail done in a mail room takes care that not every piece of mail sent to the office goes to the same group of people. After a second look at the envelope, rerouting occurs where needed.
OTRS uses so-called postmaster filters to read the email’s envelope and take further action. Depending upon, for example, a subject or sender, an email bound for the service desk could land in a sub-queue or be redirected to a completely different team to create transparency and give your customer the fastest service possible.
Use this screen to add postmaster filters to the system. The postmaster filter management screen is available in the PostMaster Filters module of the Communication & Notifications group.

Postmaster Filter Settings¶
The following settings are available when adding or editing this resource. The fields marked with an asterisk are mandatory.
Basic Postmaster Filter Settings¶
- Name *
The name of this resource. Any type of characters can be entered to this field including uppercase letters and spaces. The name will be displayed in the overview table.
Note
When adding or editing one of the postmaster filters, remember multiple filters may apply to a single mail. Rules are executed and sorted by the ASCII value of the names. Based on the sorted order in the overview, they are applied from top to bottom. Look at the ASCII table to see how to sort your names based on the ASCIIbetical order.
- Stop after match *
Postmaster filters are evaluated in ASCIIbetical order. This setting defines the evaluation of the subsequent postmaster filters.
- No
- All postmaster filters are executed.
- Yes
- The current postmaster filter is still evaluated, but evaluation of the remaining filters is canceled.
Filter Condition¶
A postmaster filter consists of one or more conditions that must be met in order for the defined actions to be executed on the email. Filter conditions can be defined for specific mail header entries or for strings in the mail body.
- Search header field … for value
Select a mail header or an
X-OTRS
header from the first drop-down list, and enter a value as search term for the selected mail header to the second field. Even regular expressions can be used for extended pattern matching.A list of mail header entries can be found in RFC5322. It is also possible to define
X-OTRS
headers as filter condition. The differentX-OTRS
headers and their meaning are the following:X-OTRS-AttachmentCount
- This contains as value the number of attachments which are contained in the email (e.g. 0 for mails without attachments).
X-OTRS-AttachmentExists
- Depending on whether attachments are included in the email this
X-OTRS
header is set toyes
, or it has ano
value if no attachments are included. X-OTRS-BodyDecrypted
- If the incoming mail was encrypted, it is possible to add a search term to look for the body of the incoming encrypted mail.
X-OTRS-CustomerNo
- Set the customer ID for the ticket.
X-OTRS-CustomerUser
- Set the customer user for the ticket.
X-OTRS-DynamicField-<DynamicFieldName>
- Saves an additional information value for the ticket on <DynamicFieldName> dynamic field. The possible values depend on dynamic field configuration (e.g. text: Notebook, date: 2010-11-20 00:00:00, integer: 1).
X-OTRS-FollowUp-*
- These headers are the same as the ones without the
FollowUp
prefix, but these headers are applied only for follow-up mails. X-OTRS-FollowUp-State-Keep
- If set to 1, the incoming follow-up message will not change the ticket state. For this purpose the header can be customized in the system configuration using option
KeepStateHeader
. X-OTRS-Ignore
- If set to
Yes
orTrue
, the incoming message will completely be ignored and never delivered to the system. X-OTRS-IsVisibleForCustomer
- Controls if the article is shown to customer users. Possible values are 0 or 1.

- Set the agent as owner for the ticket.
X-OTRS-OwnerID
- Set the agent ID as owner for the ticket.
X-OTRS-Priority
- Set the priority for the ticket.
X-OTRS-Queue

X-OTRS-Responsible
- Set the agent as responsible for the ticket.
X-OTRS-ResponsibleID
- Set the agent ID as responsible for the ticket.
X-OTRS-SenderType

X-OTRS-State-PendingTime
Set the pending time for the ticket (you should sent a pending state via
X-OTRS-State
). You can specify absolute dates like 2010-11-20 00:00:00 or relative dates, based on the arrival time of the email. Use the form+ $Number $Unit
, where$Unit
can be s (seconds), m (minutes), h (hours) or d (days). Only one unit can be specified. Examples of valid settings: +50s (pending in 50 seconds), +30m (30 minutes), +12d (12 days).Note
Settings like +1d 12h are not possible. You can specify +36h instead.

headers from trusted sources.
