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.

OTOBO uses so-called postmaster filters to read the emails 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.

Postmaster Filter Settings Example

Basic Postmaster Filter Settings

Postmaster Filter Settings - Basic

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

Postmaster Filter Settings - 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-OTOBO 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-OTOBO headers as filter condition. The different X-OTOBO headers and their meaning are the following:

X-OTOBO-AttachmentCount

This contains as value the number of attachments which are contained in the email (e.g. 0 for mails without attachments).

X-OTOBO-AttachmentExists

Depending on whether attachments are included in the email this X-OTOBO header is set to yes, or it has a no value if no attachments are included.

X-OTOBO-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-OTOBO-CustomerNo

Set the customer ID for the ticket.

X-OTOBO-CustomerUser

Set the customer user for the ticket.

X-OTOBO-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-OTOBO-FollowUp-*

These headers are the same as the ones without the FollowUp prefix, but these headers are applied only for follow-up mails.

X-OTOBO-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-OTOBO-Ignore

If set to Yes or True, the incoming message will completely be ignored and never delivered to the system.

X-OTOBO-IsVisibleForCustomer

Controls if the article is shown to customer users. Possible values are 0 or 1.

X-OTOBO-Lock

Set the lock state of a ticket. Possible values are locked or unlocked.

X-OTOBO-Loop

If set to Yes or True, no auto answer is delivered to the sender of the message (mail loop protection).

X-OTOBO-Owner

Set the agent as owner for the ticket.

X-OTOBO-OwnerID

Set the agent ID as owner for the ticket.

X-OTOBO-Priority

Set the priority for the ticket.

X-OTOBO-Queue

Set the queue where the ticket shall be sorted. If this is set, all other filter rules that try to sort a ticket into a specific queue are ignored. If you use a sub-queue, specify it as Parent::Sub.

X-OTOBO-Responsible

Set the agent as responsible for the ticket.

X-OTOBO-ResponsibleID

Set the agent ID as responsible for the ticket.

X-OTOBO-SenderType

Set the sender type for the ticket. Possible values are agent, system or customer.

X-OTOBO-Service

Set the service for the ticket. If you use a sub-service, specify it as Parent::Sub.

X-OTOBO-SLA

Set the service level agreement for the ticket.

X-OTOBO-State

Set the state for the ticket.

X-OTOBO-State-PendingTime

Set the pending time for the ticket (you should sent a pending state via X-OTOBO-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.

X-OTOBO-Title

Set the title for the ticket.

X-OTOBO-Type

Set the type for the ticket.

Warning

These headers must be manually injected into the mail by means not provided for by OTOBO. OTOBO only accepts X-OTOBO headers from trusted sources.

The Mail Account Settings defines the trust level.

Negate

If checked, the condition will use the negate search term.

Set Email Headers

Postmaster Filter Settings - Set Email Headers

In this section you can choose the actions that are triggered if the filter rules match.
