Patterns

The Patterns tab allows you to specify groups of items as a single name for use in many places within IceWarp Server. Patterns can help you to overcome string length limitations for particular places in IceWarp Server configuration (patterns can be used on those places). If you need to save longer string(s) than IceWarp Server is able to, use pattern(s).

Patterns can be used within:

• Account aliases

• Access

• Black & White filters

• Trusted IPs

• Rules (+ Content Filters)

• Bypass dialogs

• Service IP binding

• Firewalls

• {user} >Mail > Forward to

• {user} >Mail > Copy incoming mail

• {user} >Mail > Copy outgoing mail

Field	Description
Add	Click the button to add a new pattern. The Pattern dialog opens.
Edit	Select a pattern and click the button to edit this pattern. The Pattern dialog opens.
Delete	Select a pattern and click the button to remove this pattern.

The above example shows an item called Firewall containing two IP address items 192.168.*.* and 206.62.*.*

In places where patterns are allowed you can specify [Firewall] (note the square brackets) instead of the two items, so, for example, you could use this pattern in a service access definition.

Field	Description
Name	Specify a unique name for the pattern.
Items	Specify a list of items, one per line. You can include: IP addresses with masks emails and domains with masks account names with masks other patterns

Patterns Examples

For emails a1@domain.com, a2@domain.com, a3@domain.com is possible to use pattern value of a or @domain.com.

For emails b@domain.com, b@another_domain.com is possible to use b@ or just b.

You can figure out many other possibilities.
